An uneven strain model for analyzing the residual stress and interface stress in laminate composite was proposed. The analytic formulas of residual-stress in the laminate with symmetrical structure were presented and the variations of the residual-stress and interface stress with location were studied. This study revealed two important facts: (1) for a single layer in laminate, the residual stress is a function of location along length; (2) there exist normal stresses in the interface and it varies along the length direction. Experiments of mechanical properties were performed, using Si3N4/TiN-Si3N4 laminate sample with symmetrical three-layer and multilayer (2N+1), to investigate the effect of residual stress. The results suggest that the mechanical properties depend on the distribution of residual stress and is consistent with the theoretic prediction.
