CONSTITUTIVE MODEL AND FAILURE PARAMETERS OF TC4 TITANIUM ALLOY UNDER QUASI-STATIC TENSILE
Large deformation and fracture processes of materials are often involved in the finite element simulation of high-speed collision. Based on the Johnson-Cook fracture failure model, TC4 titanium alloy samples with different notch sizes were designed, and the fracture strain and stress triaxiality of...
