Elasticity#
You can use the Elasticity
component to solve the elasticity equation with or without inertia.
Whether inertia or body forces are included is determined by the Elasticity
property settings.
Gravitational body forces are included if the gravity_field
is set in the Problem
.
Table 15 lists the various elastic, viscoelastic, and elastoplastic bulk constitutive models implemented for the elaticity equation.
