Ductile failure analysis of API steel pipe using strain based failure criteria
This project was performed to propose ductile failure criteria as a function of the stress triaxiality for the API X42 steel pipes. The objective of this project is to determine the burst pressure of modeled pipe using strain based failure criteria. In this project, uniaxial tension test was perform...
