Theoretical aspects of the EURDYN computer programs for non-linear transient dynamic analysis of structural components
Description
The computer programs EURDYN for non-linear transient dynamic analysis of two- and three-dimensional structures, is described. Non-linearity arises from large displacements as well as from elastic-plastic material behavior. The finite-element displacement method is used and the equations of motion are formulated in terms of convected co-ordinates that rotate but do not deform with the elements. A lumped-explicit scheme is used to advance the solution in time. The finite-element library of EURDYN/1 includes the constant-strain triangle (plane or axisymmetric), a recti-linear beam element and a conical shell element. EURDYN/2 employs isoparametric elements for plane stress, plane strain and axisymmetric situations. EURDYN/3 deals with thin shells in three-dimensional space
