摘要: A global-local finite element method to analyze multiple delamination in composite laminates has been developed. To enhance computational efficiency, layerwise elements are used the delaminated zone and first order beam bending undelaminated zone. transition is between global local zones. postprocess utilized convert variables those of shear model. By introducing this novel matching scheme, laminated composites with delaminations can be analyzed without a significant increase memory capacity. When applied problems, buckling predictions agree well other known results.
