Modelling the shear modulus of a material.

[Sarah800]

Hi,

I am trying to model the shear of a special composite material that I have designed.
I have modeled a simple block. And simply applied a parallel force on the block. The procedure is i measure the resulted displacement and divide it by the initial length of the block.
The problem i am facing is that i get a very high value of the shear strain (more than 8 times more than it should be).
Have anyone came across that?

Thanks

is it a homogeneous composite or a laminate ?

shouldn't it be the deflection/height ?? ... in cross-section, you're changing a rectangle into a rhombus, no? (rather than elongating the rectangle)
