Abstract
Thermal singular stress problem for glassfiber reinforced plastics with surface cracks at cryogenic temperatures is considered. For the case of the crack which is normal to and ends at the interface between orthotropic elastic materials, the order of stress singularity around the tip of the crack is obtained. Fourier transforms are used to formulate the problem in terms of a singular integral equation. The singular integral equation is solved by using the Gauss–Jacobi integration formula. Numerical calculations are carried out for the cases of embedded and edge cracks, and the thermal stress intensity factors at different temperatures are shown graphically.
