Application of Hybrid Finite Elements to Structure Mechanics Problems.

Abstract

This report presents a summary of the results of this research program. A list of all publications under this contract is given. The research findings summarized here are listed under four categories: (1) rationalization and extensions of variational formulations of finite element methods, (2) development of crack elements, (3) analysis of geometrically nonlinear problems, and (4) analysis of material nonlinear problems. Two appendices which contain more detailed descriptions are (A) Creep and viscoplastic analysis by assumed stress hybrid finite elements and (B) Three-dimensional crack elements by hybrid stress model.
