Study on Stress-Strain Model of Metallic Materials with Shot Peening Residual Stress

Abstract:

Study on Stress-strain model of metallic materials with residual stress. First of all, Stress-strain model of metallic materials with residual stress was analyzed, then, derivation of a stress-strain model was done. Finally, according to the model of stress and strain analysis and derivation of results, taking diaphragm spring as an example, using methods of derivation of kinds of material obtained from this model portfolio, using finite element modeling tools, calculate the relationship between load and deformation. The test result indicated that, using the method of many kinds of material model combination can get the higher precision of calculation.
