چکیده
|
In this study, a non-associated viscoplastic flow rule (navfr) with combining von mises and tresca loci in place of yield and plastic potential functions and vice verse is presented. it is shown that the proposed navfr can be adopted to forecast the experimental events more accurate than the conventional associated viscoplastic flow rules (avfr). this outcome obtained with the aid of fully implicit time stepping scheme and discussing the other studies on plastic potential flow rules and also experimental results.
