Type

Description

$matTag

integer

unique tag identifying this material

$otherTag

integer

unique tag identifying the previously defined nD material

$sig0_11 <$sig0_22 $sig0_33 $sig0_12 $sig0_23 $sig0_13>

1 or 6 float

initial stress values. If only one is given, a volumetric strain = sig0_11 is imposed.

Notes#

It is a wrapper that imposes an inital stress to another material such that \(\sigma = f\left (\varepsilon + \varepsilon_{0}\right )\).
