INTEGRAL EQUATIONS FOR NONDESTRUCTIVE DETERMINATION OF BUCKLING LOADS FOR ELASTIC PLATES AND BARS

A simple method for defining the kernel of an integral equation associated with the buckling of elastic bars and plates is proposed. The plates and the bars may have varying stiffness and any combination of elastic boundary conditions and varying in-plane load. The buckling load may appear in the boundary conditions. The kernel has a simple mechanical interpretation. On the basis of this interpretation a nondestructive method for determination of the buckling load is proposed. By measuring the deflections and the rotations caused by a unit load, one can define the kernel experimentally, avoiding the determination of the existing real boundary conditions. Having the experimentally defined kernel, one can calculate the buckling load in a nondestructive way. (Author)
