Abstract

Presented in this study is a preliminary micro-mechanical model to simulate the possible effects of time-dependent material properties on dimensional changes in a thin composite layer. The model shows that the viscoelastic effect leads to instability after cooling has finished. This viscoelastic effect causes a cooling rate effect on the behavior of shrinkage, residual stresses and shrinkage recovery of inner layers. Time temperature superposition (TTS) included in the model stretches the time scale and indicates that dimensional stability will continue for very long times. TTS also has impact on the measurement of CTE.
