Hello,
I am modelling indentation on various polymer layers. I do this by creating various layers and assigning each layer different material properties. Job completes succesfully. However, when I go and view the results, when the indentor compresses down on the material, only the top layer is affected. The layers below are not affected at all. As a matter of fact, it seems like the top layers is going "through" thesubsequent layers rather then compressing itself and transmitting the compression force through the other layers.

Thank you in advance!

Ciao.

It sounds like there is no contact between the different layers.
I recommend one of the two following solutions:

(1) Make the different layers have common nodes at the interfaces
(2) Define contact between the surfaces of the different layers.
