<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>I'm a PhD student of Concordia University, Montreal, Canada and trying to simulate the piled raft behavor. I want to use the soil parameter of Frnakfurt clay, as used by Dr. Katzenbach, Reul and other researchers. From their different publications I found E, v, k, beta (37.67), d (42.43), K (.795), R (0.1), alpha (0), but could not find the value of Pa (the initial <SPAN id=lw_1263873200_0 class=yshortcuts>yield surface position)</SPAN>. I found the cap hardening softening plot in the publications but unable to find the parameters to use in ABAQUS.</DIV>
<DIV> </DIV>
<DIV>Pls. help me to get the value of Pa (the initial yield surface position) and the cap hardening softening curve parameters for ABAQUS. </DIV>
<DIV> </DIV>
<DIV>Thanks in advance.</DIV>
<DIV> </DIV>
<DIV>Best regards</DIV>
