✦ Synopsis

Stress analysis by means of the finite element method was done on glass-fibrereinforced plastics subjected to combined shear and compressive stresses. Two types of experimental set-up were analysed, that is, parallel and series methods, where the specimens were compressed by tilted jigs that allow the application of combined stresses on the specimens. The Tsai-Hill criterion was employed to judge the failures under the combined stresses. Different failure envelopes were obtained for the two set-ups. In the parallel system, the shear strength increased once with compressive stress and then decreased. In the series system, the shear strength decreased montonically with compressive stress. The difference was brought about by different stress distributions due to different constraint conditions.
