Mechanical Properties of 316L Stainless Steel under Different Deformation Rates Obtained by Ball indentation Method
Due to cold-working hardening in the process of nuclear power welding,the mechanical properties of the local area are changed and it is difficult to obtain accurately.The ABAQUS finite element analysis software was used to establish a three-dimensional model of indentation test under elastoplastic materials for numerical simulation.By identifying the relevant parameters in the load-depth curve and combining with the dimensional analysis,the mechanical properties of 316L austenitic stainless steel materials at different deformation rates were calculated.The results show that the plasticity of the material decreases and the hardness increases,and the mechanical properties such as yield strength,tensile strength,and hardening index,increase with the increasing deformation rates.
