1.理论分析 (1)计算模型 图1是一复合材料层板,由n层单向层铺设而成,铺层次序不一定对称于板的中面。每层的纤维方向可以不同,从z轴的正向看起自x轴反时针方向的铺层角为正。层板四边固支。冲击方向垂直于板平面。
1. Theoretical Analysis (1) Calculation Model Figure 1 is a composite material laminate, which is laid by n-layer unidirectional layers. The order of the layers is not necessarily symmetrical to the middle of the plate. The fiber orientation may vary from layer to layer, with positive lamination angles from the x-axis counter-clockwise looking from the positive z-axis. Shelf solid support. Impact direction perpendicular to the plane of the plate.
