betad

Mapdl.betad(value='', **kwargs)

Defines the stiffness matrix multiplier for damping.

APDL Command: BETAD

Parameters:

value

Stiffness matrix multiplier for damping.

Notes

This command defines the stiffness matrix multiplier β used to form the viscous damping matrix [C] = β [K] where [K] is the stiffness matrix.

Values of : β may also be input as a material property (use the BETD label on the MP command). If BETD is included, the BETD value is added to the BETAD value as appropriate (see Damping Matrices in the Mechanical APDL Theory Reference). Damping is not used in the static (ANTYPE,STATIC) or buckling (ANTYPE,BUCKLE) analyses.

This command is also valid in PREP7.
