Governing Equations
The model solves the governing equations for a general linear elastic material in a velocity-strain formulation
where
v
is the velocity,
ρ
the density,
S
the stress tensor,
E
the strain tensor,
C
is the elasticity tensor (or stiffness tensor), and
F
v
is a possible body force. The equations are valid for both isotropic and anisotropic material data.
