摘要：
The process-induced residual stress for laminated composite with metallic plate is investigated by numerical simulation during the curing process. A two-dimensional finite element model is used to compute process-induced residual stress of the laminated composite. Interface formation process between the fiber and the matrix in the longitudinal direction of composites is described by user-defined exponential function and considered in the numerical model. Numerical results show that the prediction is more accurate in the longitudinal direction of composites when the interface formation process between the fiber and the matrix is considered, which has been confirmed in the test.
