| Abstract: | A kind of three-dimensional semi-analytical finite element method is put forward for the analysis of transverse failure in cross-by laminates.The method can be applied to different shape transverse failure problems.The method has the properties of high efficiency and good precision.When crack expanding problem is studied,a high efficiency semi-analytical matrix perturbation method is put forward.An idiographic crack problem of laminates are performed in the examples,some important conclusions are obtained. |
