contact with friction
Posted Dec 15, 2010, 3:25 PM EST Structural Mechanics & Thermal Stresses Version 4.0a 2 Replies
My setup includes:
a) a block that is .1m tall, 2m wide and 10m long
b) a block that is .1m tall, 1m wide and .75m long
block b is sitting on top of and at the edge of block a.
(there is a .01m distance between the surfaces so that the two blocks do not form a union)
Constraints (structural mechanics):
I applied a fixed constraint to block a
I have the two blocks set up as a contact pair, and have a contact pair constraint set with dynamic friction
I have a boundary load applied to the side of block b that is intended to push it along the length of block a
I have a boundary load applied to the top of block b to assert a gravitational force
I have the materials set as 1018 steel
I have a finer mesh on block a
Here are the problems I'm having:
- the displacement of block b doesn't change as the dynamic friction coefficient is increased.
- block b seems to be protruding through the contact surface of block a
Thanks for any tips or suggestions !
