Abstract
It is necessary to get a fundamental data of FW・RP cylinder setting up a side circular hole for design of mechanical structures transmitting torsion load. In this study, the torsion rigidities near the side hole were measured by static torsion tests. Moreover, the properties of FW・RP cylinder with a side hole were calculated by original FEM program that is able to simulate FW・RP cylinder. As a result, it is concluded that each of stress distribution and each of Normalized stress σ_u/σ_s has closely relation with each of the following parameters, (1) Fiber orientation rlivArtinn : θ, (2) Daimeter of a side circular hole: a.
