Dynamic Mechanical Property of a Steel
In order to realize the dynamic mechanical property of a steel, the quasic-static and dynamic compressive and tensile mechanical tests of a steel are carried out. Based on the stress-strain curves of the steel, the constitutive relation is presented and it can be used to describe compressive and tensile mechanical property correspondently. The stress-strain curves at different strain rate and the obtained dynamic constitutive relationship show that the flow stress of the steel is increased with strain rate increased. The dynamic tension experimental results show that failure strain and stress of the steel are increased small with strain rate increased, and the fracture of tension sample is ductile fracture.
