AXISYMMETRICAL THERMOELASTIC RESPONSE OF A COMPOSITE CYLINDER CONTAINING AN ANNULAR MATRIX CRACK

An elasticity solution to the problem of an annular crack in a concent ric cylinder under a remote uniform axial strain and constant temperat ure change is found. Stress intensity factors at the crack tips and th e stresses at the interface are studied to determine the nature of the crack growth in the composite. These parameters are studied as a func tion of the elastic moduli and the thermal expansion coefficients of t he constituents, the fiber volume ratio, crack geometry, and interface properties.
