Crystal plasticity simulation of the hydrostatic bulge test

In this article the finite–strain deformation of a membrane under hydrostatic pressure is investigated using a rate-dependent polycrystal plasticity formulation based on Taylor assumptions, where each material point in the sheet is considered to be a polycrystalline aggregate of a large number of grains. A finite element program is developed for arbitrary die aperture geometries and numerical results are generated for a circular specimen using …
