Hello everyone:

I want to ask the mechanism of O. Cell.Velgrad, What is the loading mechanism of O. Cell.Velgrad, and if it is used to simulate the simple shear test(like O.cell.velGrad=Matrix3(0,0,0, 0,0,0, 0.02,0,0)), is it reasonable?

Also there is another way to simulate the simple shear test.which the sample is sandwiched between two plates..the top plate was secured to keep the initial height of specimen and simple shear was applied by moving the bottom plate.

What are the differences between the above two methods of simulating a simple shear test..

Thanks!
