noCompression

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

noTension

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

temperatureDependency

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

dependencies

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

moduli

An odb_String specifying the time-dependence of the elastic material constants. Possible values are "INSTANTANEOUS" and "LONG_TERM". The default value is "LONG_TERM".
