There is a common difficulty in elastic-plastic impact·codes such as EPICNONSAP.etc..Most of these codes use the simple linear functions usually taken from
In this paper the method and technique of the diagonalization are employed totransform a vector second-order nonlinear system into two first-order approximatedi
In this paper,the general formulation of a new proposed iteration algorithm of mixedBEM/FEM for eigenvalue problems of elastodynamics is described.Approximatefu
