I'm modelling some effects of changing acceleration on sandstone, and I'd like to add the damping effect listed in the mechanical properties of the CAE material dialogue.
The parameters are alpha, beta, structural and composite. I've done some web research and can't seem to find a formulation of the structural damping law that uses anything like those parameters. The ABAQUS manual doesn't help much either.
Can someone direct me towards some typical parameters for some simple materials, like sandstone, granite, cermaics, etc., or even better, towards an explanation of these parameters?
Many thanks in advance
