Abstract:The paper analyzed a steel thick cylinder, established a bilinear kinematic hardening model based on the von Mises yield criterion. We also considered the parameters of the material yield limit, the autofrettage pressure, working pressure and cylinder diameters, studied of a response surface model to predict design parameters. We firstly used the optimal Latin Hypercube method to acquire the sample points. Then, we established a response surface model with these points. We also employed cross-validation error analysis for error analysis. The results tested the feasibility of this method in solving such problems.
