No penetration contact causing bouncing effect between two bodies.

I'm running a simulation pushing a screw into a wooden block to test how deep the helices penetrate the block. There is a constant 150 N force in the direction of the block and the screw helices have a no penetration contact with friction. Ultimately the simulation is failing and watching the resulting animation shows the screw bouncing back and forth off the block multiple times instead of just pressing into it. The fixtures used are fixed geometry to the back of the block and a rolling fixture to the sides of the screw. I'm running a nonlinear static simulation with a plastic-von mises model for the wood's material. Does anyone know how to fix this bouncing effect? I can post the files if necessary.
