| Abstract: | The implications of somewhat unfamiliar thermo-elastic phenomena in laminated fibre composites are discussed in physical terms. By this approach certain simplified relationships are developed and the attendant physical interpretations are encouraged. Specifically, laminated flat plates exhibiting finite, negative thermal expansion coefficients and hoop-wound composite rings subjected to temperature changes are treated so as to emphasize the importance of the phenomena. It is also shown that the translaminar expansion coefficient is an important parameter in the hoop-wound ring which develops significant circumferential stresses when subjected to uniform changes in temperature. |
