FRP円筒かくの圧縮と曲げ強度

概要

Fracture behaviors under axial compression or bending were studied for macroscopically isotropic FRP cylindrical shells having R/t<100. The results obtained are as follows. (1) In both cases of axial compression and bending of the cylindrical shells, there are two types of fracture behaviors depending upon the R/t ratio of cylindrical shells; buckling and compressive fracture types. (2) When both compressive and flexural strength are expressed by use of the buckling coefficient, the coefficient changes considerably because the fracture behaviors vary with the ratios of R/t and L/R of a cylindrical shell.
