Abstract |
|
Triaxiality is the ratio of hydro static pressure to the von-mises effective stress. As the triaxiality of the stress state influences greatly the amount of plastic strain, a material may undergo the ductile failure before actual failure occurs. This study gives the mathematical model for crack tip opening displacement (CTOD) based M-criterion model and used to study the effect of CTOD on stress Triaxiality and compare with simple M-criterion. Finite element analysis of single edge cracked rectangular plate is carried out in order to support the relations developed and validate the work. Optimization is carried out in order to determine maximum stress triaxiality and corresponding CTOD and crack initiation angle. |
