session.odbs[name].materials[name].Elastic

Required argument

table

A sequence of sequences of Floats specifying the items described below.

Optional arguments

type

A SymbolicConstant specifying the type of elasticity data provided. Possible values are:

A Boolean specifying whether compressive stress is allowed. The default value is OFF.

noTension

A Boolean specifying whether tensile stress is allowed. The default value is OFF.

temperatureDependency

A Boolean specifying whether the data depend on temperature. The default value is OFF.

dependencies

An Int specifying the number of field variable dependencies. The default value is 0.
