Extensive Library of Material Models

It is vital to understand and accurately characterize material behavior while designing or analyzing an engineering application. ANSYS Explicit Dynamics solutions provide a vast library of mathematical material models to aid the user in simulating virtually all kinds of material behavior as shown in the table below. In addition, in order to aid in finding parameters for these materials models, ANSYS also provides a set of curve-fitting tools.
