Can you calculate a new shear modulus for a design in Solidworks 2021 Simulation?

I have created an interwoven mesh wick (see photos attached) in Solidworks 2021 and ran a stress simulation where one end of the design is pulled a designated amount while the other end is fixed/on rollers to allow for poisson ratio calculations. I was wondering if there is any way to calculate a new shear modulus from this deformation as the material shear modulus is no longer accurate for such a design. Many thanks.

Hello again David!

One way to get what I think you need is to simply apply their definitions (only to a whole piece, rather than just a chunk of material).

If you wanted to replace your part (mesh) with some kind of "equivalent material", it would have a "Poisson's ratio" which, by definition, arises from dividing the lateral shrinkage experienced by the part for a given stretch: Poisson = Lateral shrinkage / Longitudinal elongation.

Both parameters are obtained from the post-processing of your simulation, it is simply a matter of dividing them numerically.

And for a module (also apparent) of cut, you would apply the definition:
TAU = G*GAMMA
SHEAR STRESS = TRANSVERSE MODULE OF ELASTICITY * ANGLE OF DISTORTION
If you apply a shear stress to a sector of your mesh (fixing one face and placing a tangential load on the opposite face) you can observe how much the angle between its (initially straight) sides is distorted. Operating with these two values you can obtain an apparent G module (for the whole piece).

I hope I have understood your need correctly!
