1.4.5. Mode-Dependent Damping Ratio
Mode Dependent Damping Ratio gives you the ability to specify different damping ratios for different
modes of vibration. It is specified with the MDAMP command and is available only for the spectrum
and mode-superposition method of solution (transient dynamic and harmonic analyses).
1.4.6. Viscoelastic Material Damping
Viscoelastic materials have a frequency-dependent complex modulus in the harmonic domain.The
imaginary component of the complex modulus, also called the loss modulus, results in a material
damping matrix that is added to any other forms of damping defined in the analysis.
1.4.7. Element Damping
Element damping involves using element types having viscous damping characteristics, including but
not limited to COMBIN14,COMBIN37, and COMBIN40.
1.5. Solution Method
The ANSYS family of products uses the h-method for solving structural problems. The h-method can
be used for any type of analysis.
