... validated finite-element models for analyzing the classes of shearing processes. The article also discusses the use of microstructural characterization with stereology to render three-dimensional volumetric parameters. It concludes with information on the numerical simulation of an edge-shearing process...

... with strain rate, initial microstructure and prior thermomechanical history, chemistry, and the type of testing performed. Indeed for example, the tensile stress-strain curve of a material is generally not exactly similar to its compressive counterpart. In order to ensure the best modeling results possible...

..., it is only helpful when an analog exists, such as plasticine for hot steel, and when the damage is not caused by a microstructural-level phenomenon but rather by a stress- or strain-state effect. For example, central bursting during extrusion can be physically modeled because it is caused by tensile stresses...
