| description | In this paper, a novel method was proposed to measure the residual stress and plasticity parameters of metal materials with yield plateau through continuous spherical indentation test. The indentation energy was selected as the indentation parameter to establish a dimensionless equation between the residual stress and material parameters through dimensional analysis method. The effects of residual stress and plastic parameters on the indentation response tests are studied, and the dimensionless function expressions are determined respectively when the specimen with or without residual stress based on the finite element analysis data of different residual stress levels. Based on the self-established inverse analysis, the yield strength ( ${\sigma }_{y}$ ), strain hardening exponent (n), ratio coefficient (a) and residual stress ( ${\sigma }_{r}$ ) can be obtained through indentation test. At last, the validation of the method presented in this paper was verified by simulating the material (SS400 and SM490) with the known material parameters. |
