Modelling the shear modulus of a material.

Modelling the shear modulus of a material.

Modelling the shear modulus of a material.

(OP)
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

RE: Modelling the shear modulus of a material.


Sarah800, there are several things that might be causing this:

1. Depending on what release of ProE/Mechanica you are using, you might have a mismatch of units between ProE and Mechanica. (http://coach2.mbar.dtu.dk/CADTRN-130692/CADTRN/wil...).
2. I'm assuming your composite consists of multilayer layup, correct? if so, did you model the individual layers in your block model or did you use overall homogenized properties? This will cause major difference in the outcome.
3. Do you know that your analysis is converging? Is the mesh fine enough?

I hope this helps,
