Tensile behavior and constitutive model of 35CrMoA steel

摘要

The tensile properties of 35CrMoA were tested by rotating disk tensile impact testing machine.The fracture appearance and metallurgical structure were observed.the stress-strain curves of 35CrMoA at strain rate range from 10-2/s to 103/s were obtained.The influence of strain rate on mechanical properties and microstructure of the 35CrMoA steel was analyzed.Based on the mechanical properties of the 35CrMoA,the JC constitutive parameters were fitted.
