Plasticity materials implement their yield behavior by combining them with hardening laws. The material definition sets the equation of state properties for the material and the selected hardening law determines the yield criterion.
Selecting a Hardening Law
Hardening laws are assigned to materials within their material definition. When using NairnFEAMPM or NairnFEAMPMViz, a a hardening law is added within a material definition block as follows:
Material ID,name,type
.
plasticLaw (Law_Name or number)
(Law Properties
.
.
Done
where
<Material Type='#' Name='name'>
.
<plasticLaw>(Law_Name or number)</plasticLaw>
(Law properties)
.
</Material>
where the plasticLaw command selects the law (using the law name or number from the table below). The law selection is followed by commands to set any properties specific to that law.
