      <title>ON SUPERPOSED SMALL DEFORMATIONS ON A LARGE DEFORMATION OF AN ELASTIC COSSERAT SURFACE</title>
      <link>https://trid.trb.org/View/3746</link>
      <description><![CDATA[Within the scope of the theory of a Cosserat surface, this paper is concerned with small deformations superposed on a large deformation in elastic shells and plates together with some related aspects of the subject.  Special attention is given to problems of stability and vibrations of initially stressed isotropic plates.  (Author)]]></description>

      <title>ADDED MASS ANALYSIS OF ELASTIC AXISYMMETRICAL ROTATIONAL SHELL IN WATER</title>
      <link>https://trid.trb.org/View/440517</link>
      <description><![CDATA[A numerical procedure for calculating the added mass of a submerged elastic axisymmetrical rotational shell is described, The purpose of the paper was to obtain the added mass which can be combined directly into a structural mass matrix of finite element method (FEM).  Added mass is axisymmetrically analysed by the boundary element method (BEM) with respect to nodal displacements including the rotational degree of freedom.  The obtained added mass is transformed into FEM type fluid mass matrix, so that the superposition on the structural matrix becomes possible.  Using the calculation procedure of added mass, natural frequency and mode are investigated for cylindrical shell models with variations in water depth ratio.  The validity of the calculation method of added mass was examined by the comparisons of natural frequencies with experimental data.]]></description>

      <title>SHELL THEORY FROM THE STANDPOINT OF FINITE ELASTICITY</title>
      <link>https://trid.trb.org/View/57396</link>
      <description><![CDATA[This is an account of the nonlinear theory of thin shells from the standpoint of finite elasticity, together with a brief summary of some related recent researches on the subject.  The development of the basic theory, as well as a discussion of constitutive equations for elastic shells, are presented via a direct approach on the basis of a continuum model known as a Cosserat surface rather than from the three-dimensional equations of nonlinear elasticity.]]></description>

      <title>FORCED PLANE STRAIN MOTION OF CYLINDRICAL SHELLS-A COMPARISON OF SHELL THEORY WITH ELASTICITY THEORY</title>
      <link>https://trid.trb.org/View/17238</link>
      <description><![CDATA[A radially directed load is suddenly applied to a portion of the outer surface of a circular cylindrical shell which responds in a state of plane strain. An analytical solution for the resulting dynamic response is obtained within the context of linear elasticity theory, Flugge shell theory, and an improved shell theory. A comparison of results for specific loading conditions indicates that the improved theory is far superior to the Flugge theory in terms of predicting both the magnitude and characteristics of the response. However, as expected, neither shell theory satisfactorily predicts the wave character of the initial response. (Author)]]></description>

      <title>THE EFFECT OF GEOMETRIC NONLINEARITIES ON THE CREEP BUCKLING TIME OF AXIALLY COMPRESSED CIRCULAR CYLINDRICAL SHELLS</title>
      <link>https://trid.trb.org/View/17161</link>
      <description><![CDATA[A correction is given to the small-displacement theory of the axisymmetric creep buckling of axially compressed circular cylindrical shells.  The correction takes into account the possibility of a non-axisymmetric elastic snap through in agreement with Koiter's theory after a sufficient amount of axisymmetric permanent deformation has developed in consequency of creep.]]></description>

      <title>DYNAMIC BUCKLING OF THE ELASTIC CYLINDRICAL SHELL SUBJECTED TO IMPULSIVE LOADING</title>
      <link>https://trid.trb.org/View/15897</link>
      <description><![CDATA[A periodic, Fourier series solution is presented for the nonlinear dynamic response of an impulsively loaded, elastic cylindrical shell.  This result has been obtained by a new application of the quadratic form of Newton's method; in this modification the frequency is considered to be the basic independent variable, and analytical corrections are obtained when solutions of the linear variational equations are nonperiodic.  The solution presented here is shown to consist of a slowly varying function modulating a rapidly varying function, and is compared with results obtained by direct numerical integration.]]></description>

      <title>ON UNIQUENESS IN THE LINEAR THEORY OF ELASTIC SHELLS AND PLATES</title>
      <link>https://trid.trb.org/View/3745</link>
      <description><![CDATA[A recent paper by the authors contains an approximate linear theory for thermoelastic shells (and plates) which is derived from the three-dimensional equations.  Under isothermal conditions, the equations of this theory are of an elastic Cosserat surface.  The present paper is mainly concerned with a uniqueness theorem for the solution of the initial mixed boundary-value problem characterized by the equations of the above mentioned theory for thermo-elastic shells.

      <title>DISPLACEMENTS AND FINITE-STRAIN FIELDS IN A HOLLOW SPHERE SUBJECTED TO LARGE ELASTIC DEFORMATIONS</title>
      <link>https://trid.trb.org/View/14021</link>
      <description><![CDATA[The paper presents the fields of displacements and strains in a hollow sphere diametrically loaded to seven levels of loads. Polyurethane rubber was used to make the hollow sphere and grids and moire gratings were printed on a meridian plane to measure displacements. The maximum applied vertical displacement reduced the outer diameter of the hollow sphere by about 20 percent. It was found that the horizontal displacement of the ends of the horizontal diameter divided by its deformed length is linear up to that load. Strains were obtained by photographic differentiation. Strains obtained for low levels of load were compared at two points of interest to those obtained using a series by Golecki for the inside boundary, and found appreciably lower. Results are presented in terms of dimensionless loads and Eulerian strains. The largest Eulerian strain recorded is about 30%, the smallest is of the order of 0.001. Stress distributions will be given in another paper. (Author)]]></description>

      <title>OPTIMAL DESIGN OF SUBMERGED ELASTIC CYLINDRICAL SHELLS</title>
      <link>https://trid.trb.org/View/14051</link>
      <description><![CDATA[The report deals with the problem of optimal design of submerged elastic cylindrical shells for maximum pressure. Approximate solution is obtained by the Rayleigh-Ritz method within the extent of presumed form of distribution function of shell thickness. Optimal configuration of the shell is found for a wide range the length-radius-ratio of the shell. (Author)]]></description>

      <title>CORRELATION OF DISPLACEMENTS IN THIN ELASTIC SHELLS HAVING RANDOM INITIAL IRREGULARITIES</title>
      <link>https://trid.trb.org/View/10114</link>
      <description><![CDATA[Initial imperfections have a substantial effect on the behavior of thin elastic shells subject to a load.  The large spread of experimental critical forces is due to these imperfections.  The report treats initial deflections as a random field.  Assumptions are introduced on the smallness of the deflection scale and the scale of their correlation compared with the characteristic middle surface measurements; there is also one for the homogeneity of the initial irregularity field.  Equations obtained by linearizing shell theory equations in the initial stage region are used.  (Modified author abstract)]]></description>

      <title>DYNAMIC PLASTIC BUCKLING OF COMPLETE SPHERICAL SHELLS</title>
      <link>https://trid.trb.org/View/11203</link>
      <description><![CDATA[A theoretical investigation is undertaken into the dynamic instability of complete spherical shells which are loaded impulsively.  The linear elastic, elastic-plastic and rigid-plastic material idealizations are used in the various theoretical procedures.  The threshold velocities for the elastic and rigid-plastic models are larger than those for cylindrical shells having the same R/h ratios and material parameters, while the critical mode numbers are similar.]]></description>

      <title>ELASTIC STRESSES DUE TO AXIAL LOADS ON A NOZZLE WHICH INTERSECTS A CYLINDRICAL SHELL</title>
      <link>https://trid.trb.org/View/8995</link>
      <description><![CDATA[A collocation method was developed in order to describe the elastic behavior of two normally intersecting cylindrical shells. The intersecting shell (nozzle) was subjected to an axial load and the intersected shell (vessel) was simply supported at both ends.  It was observed that the numerical procedure predicted stress distributions which exhibited encouraging agreement with the corresponding experimental tests of Cranch and Dally on shell intersections with small radius ratios.

      <title>HIGHER-ORDER SHELL THEORY FOR THICK CIRCULAR CYLINDERS UNDER ARBITRARY LOAD AND BOUNDARY CONDITIONS</title>
      <link>https://trid.trb.org/View/9204</link>
      <description><![CDATA[Thick shell equations of circular cylinders under axisymmetric load are developed by assuming a stress and displacement state that is a generalization of the classical thin-shell theory, i.e. the in-plane stresses contain, in addition to the classical membrane and bending stress, resultants. The governing differential equations and the associated boundary conditions are obtained by utilization of Reissner's variational principle in conjunction with the generalized stress and displacement state. Comparison of results obtained from known elasticity solutions shows that the present solution accurately represents the stress and displacement states for shells with mean radius to thickness ratios of the order of 3.0.

      <title>THE THEORY OF SHELLS AND PLATES. PART I: KINEMATICS AND BASIC PRINCIPLES</title>
      <link>https://trid.trb.org/View/1721</link>
      <description><![CDATA[This report, the first of two parts, deals chiefly with kinematics and general principles for shells, both by direct approach (i.e., via the theory of a Cosserat surface) and from the three-dimensional equations of the classical continuum mechanics.  Chapter B contains a general development of kinematics of shells and shell-like bodies while Chapter C is concerned with conservation laws, local field equations and thermodynamical aspects of the subject. Although all developments are carried out in the context of the nonlinear theory, various results appropriate to the linearized theory are also discussed.]]></description>
