Title
-
A General Approach to Problems of Plasticity and Large Deformation Using Isoparametric Elements
-
Description
-
A unified formulation of large deformation, large strain and plasticity problems is given. Lagrangian forms are preferred but an alternative Eulerian system is given. Various solution schemes are discussed and a program capable of dealing with alternatives is outlined. lsoparametric formulation is shown not only to possess merits of economy but to be highly versatile in the Lagrangian and Eulerian formulations of materially and geometrically nonlinear problems.
