Benefits of Using Lode Angle Dependent Fracture Models to Predict Ballistic Limits of Armor Steel

Benefits of Using Lode Angle Dependent Fracture Models to Predict Ballistic Limits of Armor Steel

Ductile fracture experiments are carried out at different stress states, strain rates and temperatures on a range of flat Mars 300 steel specimens to calibrate both a plasticity and a fracture model. To predict the onset of fracture a stress state and strain rate-dependent Hosford–Coulomb fracture i...
