+ 2012/04/02: step-44 — a finite strain + elasticity solver +
+
+ step-44, contributed by Andrew McBride and Jean-Paul + Perlteret, demonstrates one approach to modelling large + deformations of nearly-incompressible elastic solids. The + elastic response is governed by a non-linear, hyperelastic + free-energy function. The geometrical response is also + nonlinear, i.e., the program considers finite deformations. +
