Experimental and Numerical Investigations into the Failure Mechanisms of TRIP700 Steel Sheets

Experimental and Numerical Investigations into the Failure Mechanisms of TRIP700 Steel Sheets

The formability and failure behavior of transformation-induced plasticity (TRIP) steel blanks were investigated through various stress states. The forming limit diagram (FLD) at fracture was constructed both experimentally and numerically. Numerical studies were performed to evaluate the applicabili...
