I am working on an explicit dynamics simulation in which two surfaces are meant to interact with each other through friction, both surfaces being about 5mm x 30mm. I have all the contact settings with the desired friction coefficients etc. The two surfaces are forced together using an normal pressure of different magnitudes where I am expecting there to be a greater influence on the interaction between the two surfaces as the pressure increases from 0 to about 50kPa. However, no matter what I do there is no difference in the results when the pressure is applied and when it is not.
Is there another solver I should be using or settings that I should change for the frictional interaction to be more accurately calculated or is this a limitation of the ANSYS software. Thank you for the help!

You meant Explicit Dynamic in Workbench, AUTODYNE or maybe LSdyna?There are 3 explicit solvers for structural mechanics.
If You use Workbench try switching to transient structural (ANSYS). Most of settings should be transferred automatically from Explicit Dynamics.

You can also use Static Structural to evaluate the frictional force for relative sliding motion of two parts.
