A Mixed Updated Lagrangian Formulation for Plane Elastic Problems

CODEN: JCTRER

Abstract

A mixed finite-element model based on the incremental nonlinear theory of solid bodies is developed and its numerical accuracy is evaluated by applying the model to a number of plane elastic problems. The theoretical basis of the finite-element model is developed using a mixed updated Lagrangian formulation. The mixed model contains the displacements and stresses as the nodal degrees of freedom. Such mixed models prove to be convenient in the solution of contact stress problems.
