摘要:
应用Dugdal Barenblet概念探讨了3点弯曲受力状态下,纤维正交排列复合梁的凝合区结构。在常值的内聚力假定下,计算了Ⅰ型深裂纹的凝合区尺寸。给出了凝合区尺寸依赖于附加应力的关系曲线。其结果与WEK断裂模型所估计的损伤区尺寸颇为一致。
Abstract:
Cohesive zone structure of composite beam with orth woven fibers in a state of three points bending was investigated by the idea of Dugdal Barrenblett. Cohesive zone sizes of deep type Ⅰ crack were calculated assuming that cohesive force is constant.Curve
