<P><SPAN style="FONT-SIZE: 9pt; FONT-FAMILY: Tahoma">As you know the available coulomb friction model in Abaqus assumes zero cohesion for contact surfaces. I would like to use the VFRIC subroutine or any other method to consider the cohesion effect in the friction model. If anybody has an experience with this problem or an idea to solve it, please send it to me.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p></SPAN></P>
