Analysis of Elastic-Plastic Impact Involving Severe DistortionsSource: Journal of Applied Mechanics:;1976:;volume( 043 ):;issue: 003::page 439Author:G. R. Johnson

Abstract: A Lagrangian analysis technique is presented for two-dimensional axi-symmetric impact problems involving elastic-plastic flow. This technique is based on a triangular finite-element formulation rather than the quadrilateral formulation generally used in comparable finite-difference methods. For impact problems involving severe distortions, the triangular element formulation is better suited to represent the severe distortions than is the traditional quadrilateral finite-difference method. Included are the formulation of the technique and illustrative examples.
