betad

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

Defines the stiffness matrix multiplier for damping.

Mechanical APDL Command: BETAD

Parameters:

valuestr

Stiffness matrix multiplier for damping.

Notes

This command defines the stiffness matrix multiplier \(equation not available\) used to form the viscous damping matrix \(equation not available\), where \(equation not available\) is the stiffness matrix.

Values of \(equation not available\) can also be input as a material property ( mp,BETD or tb,SDAMP,,,,BETD). If BETD in either form is included, the BETD value is added to the betad value as appropriate. (See Material Damping Damping Matrices antype,STATIC) or buckling ( antype,BUCKLE) analyses.

This command is also valid in PREP7.
