Description of the Book:

The development and evaluation of new theoretical and numerical approaches for strongly nonlinear finite element analysis are reported. The element technology uses interior nodes to create higher order in-plane displacement forms needed for nonlinear strain calculation. Several solution procedure types are discussed, based on an updated total Lagrangian formulation. Progress with this approach and current capability levels are discussed. (Author
