DynamicStressDivergenceTensors

Residual due to stress related Rayleigh damping and HHT time integration terms

Description

This class computes the stress divergence and the stiffness proportional Rayleigh damping for structural dynamics problems. Each DynamicStressDivergenceTensors input block computes force in one direction. So, a separate DynamicStressDivergenceTensors input block should be set up for each coordinate direction. The DynamicSolidMechanics action automatically sets up the DynamicStressDivergenceTensors input block in all coordinate direction. More information about the residual calculation and usage can be found at Dynamics.
