This paper presents a new and convenient process for determining the material plasticity parameters of metal materials through an indentation test conducted using a Rockwell testing machine and FE analysis. Identified parameters almost coincide with practical values. The proposed method can be used to evaluate the characteristics of materials on the order of micro to millimeters. First, the P-h curves of the indentation are determined by experiment. Second, FE analysis of the indentation test assuming plastic hardening behavior in power-law hardening material is specified by the stress-strain curve. The FE model consisted of the test piece material and the indenter with a spring element considered the elastic deformation of the measuring system. The material parameters can be identified based on the curve fit using the polynomial function consisting of material parameters. The best solution is determined by using the response surface methodology. For identification example using steel and cupper alloy, the estimation of the plastic and elastic properties are possible for practical use.

In this study, we developed a finite element simulation program for a three-dimensional stress analysis of the rim of a road bike wheel. The cross-sectional model of the rim structure is created based on the boundary data of the rim and a three-dimensional model is created by extruding the cross-sectional model. Aluminum alloy, generally used for the rim of the road bike wheel, is assumed as the material of the rim because it is inexpensive and isotropic material.
