A LAGRANGIAN FINITE DIFFERENCE METHOD FOR TWO-DIMENSIONAL MOTION INCLUDING MATERIAL STRENGTH

Abstract

One- and two-space dimensional finite-difference schemes for the Lagrangian numerical solution of problems in the motion of solids, including material strength, are presented. Two-dimensional rectangular cartesian or cylindrically symmetric problems may be handled. Results of sample calculations are appended to illustrate the effect of material strength.
