linear_elastic

Description

This behavior class provides classical linear elastic behavior with optional thermal deformation. The behavior understands two “blocks” from which it is defined.

Syntax

***behavior linear_elastic [ modifier ] \(~\,\) **elasticity ELASTICTY [ **thermal_strain THERMAL_STRAIN ]

By default there is no thermal dilatation in the model.

Example

Two examples of linear elastic behavior follow:
