ANSYS Mechanical Solutions - Technology

Materials Technology

ANSYS Mechanical solutions offer the complete range of linear and nonlinear material models required for accurate representation of material behavior in the real world. The material behavior is independent of the type of elements used in the FE model. In addition an advanced curve fitting toolkit offers accurate conversion of nonlinear material data from experimental to mathematical model for analysis. A comprehensive list of material models supported by ANSYS is given below:

Rate-Independent	Linear	Isotropic
		Orthropic
		Anisotropic
	Nonlinear	Multilinear
	Hyperelastic	Neo-Hookean
		Mooney-Rivlin
		Polynomial
		Ogden
		Arruda-Boyce
		Gent

In addition to the above material models for analysis, ANSYS supports a curve fitting toolkit for converting experimental data into the numerical fit and material model for analysis. Currently ANSYS supports curve fitting for the folllowing materials:

Hyperelastic materials
Creep materials
Viscoelastic materials

Temperature dependency is supported for all three behaviors.
