How do I do simulation of shear and pressure waves propagation in solid using COMSOL Multiphysics?

I want to do simulation of pressure (longitudinal) and shear (transversal) waves propagating in solid in COMSOL Multiphysics using Solid Mechanics physics. Is it possible to do it in 2D geometry?...

How to do FEA modeling of piezoelectric material with incomplete piezo properties from PZT manufacturers datasheet?

In PZT manufacturer's datasheet, it is often found that they only provide part of the complete piezo properties.For example:1. Elasticity matrix. The piezo datasheets only provide Y_33 and Y_312....

How do I include electromechanical coupling coefficient in piezoelectric COMSOL simulation?

PZT manufacturers often put electromechanical coupling coefficient (k) [dimensionless] in their data sheets. This coefficient shows how much electrical energy converted into mechanical energy, and...

How to check the rheological and structural stability of a system basically a blend of polymer and newtonian oil?

The polymer is a type of PDMS elastomer which will have crosslinking by heating. The oil is less dense than the polymer, hence may separate due to density difference.The oil has a quite low...

Any mathematical model of PDMS elastomer crosslinking process?

Some PDMS elastomer, e.g. Sylgard 184, needs heat for curing/crosslinking process after the prepolymer and crosslinker are mixed. Is there any mathematical model which describe the process as a...
