Abstract
When structures are designed, the stress analysis using FEM is carried out at first, and the most desirable structure is obtained from the computational results. When the effect on human sense is considered for constructing composite structures as in the cases of tennis racket, golf shaft and fishing rod, the distribution of curvature under stress has to be kept in mind because the deformation at use is an important design parameter.
A new method is suggested to realize the deformation with a uniform distribution of curvature in this paper. In order to evaluate this proposed method, the computational results were compared with the experimental ones. It was recognized that these results agreed very well. As an example, the new method was applied to design a composite chair made from a stampable sheet. As the result, an optimum chair design with a uniform distribution of curvatures was obtained.
