Extensive Library of Material ModelsIt is vital to understand and accurately characterize material behavior while designing or analyzing an engineering application. ANSYS provides a vast library of mathematical material models that aid the user in simulating various kinds of material behavior, such as elasticity, viscoelasticity, plasticity, viscoplasticity, cast iron plasticity, creep, hyperelasticity, gaskets and anisotropy. These constitutive models can be used to simulate various kinds of materials such as metals, rubber, plastics, glass, foam, concrete, bio-tissues and special alloys. In addition, to aid in finding parameters for these materials models, ANSYS provides a set of curve-fitting tools. The virtual crack closure technique (VCCT) allows computation of energy-release rates for two-dimensional continuum and 3-D continuum elements. Two-D elements also support crack growth simulation.   Many material models are available such as shape memory allow for stent analysis.
