ADVANCES IN FINITE ELEMENT PROCEDURES FOR NONLINEAR DYNAMIC RESPONSE

The objective in this presentation is to briefly survey some recent developments in finite element procedures that we have pursued to solve dynamic problems more accurately and more efficiently, and to solve new classes of problems. We present some developments regarding the finite element analysis of shells, the solution of wave propagation problems with mode conversions, the time integration in long-time large deformation analyses, the solution of normal modes of proteins with the subspace iteration method in nonlinear conformations, and fluid flow-structure interactions.
