Do any of you know the Elasticity matrix,voigt notation of PDMS? PDMS can have a large range of properties depending on the monomer to hardener ratio. Also, I am not aware that PDMS would have to be modeled anisotropically, you can try isotropic settings and avoid directly having to input...
As a result, the matrix C is asymmetric, indicating that the beam violates Maxwell-Betti reciprocity, even at zero frequency. For our metabeam, we measure the moduli via COMSOL simulations in which we apply controlled displacements at finite frequency to the front and back faces of a single ...
