Inertial Force Beam

Calculates the residual for the interial force/moment and the contribution of mass dependent Rayleigh damping and HHT time integration scheme.

Description

This class computes the component of the inertial force/torque and mass/inertia proportional Rayleigh damping for the beam element due to mass/rotational inertia. Please look at C0TimoshenkoBeam for details.
