BASIC RESEARCH IN CRASHWORTHINESS II-DYNAMIC ANALYSIS OF ELASTO-PLASTIC SPACE FRAME STRUCTURES

Dynamic inelastic structural analysis is presented for space frames under general dynamic environments. A computer program DEPASF, based on the analysis, has been developed. The small displacement theory is employed and the plastic deformation is restricted to the element and cross sections. The integration is carried out step-by-step by a Runge-Kutta method. An algorithm for the linear acceleration method is also provided. Due to the small displacement theory, application to automobile crashworthiness is restricted to low speed collisions in which large deformation and large rotation do not occur. Examples of plane and space frames illustrate the efficiency of the associated computer program. Portions of this document are not fully legible.
