Abstract
An axisymmetric fiber/matrix composite cylinder of finite length and diameter, subjected to a stationary and homogeneous change in temperature, with respect to the unstressed state, is considered. Emphasis is on SD-efFects in the state of stress, which are not covered by 2D-models, but have a strong impact on the kind of fracture and failure processes that may develop. In particular a thermally induced axial debonding process between fiber and matrix is analysed in detail, including the effects of contact and sliding friction along the crack faces. 1. Introduction Aircraft- and spacecraft structures manufactured from composite materials are frequently subjected to superimposed mechanical and thermal loadi
