带圆孔复合材料层合板应力集中系数的研究

The Study on the Stress Concentration Coefficient of the Composite Laminates with a Circle Hole

利用实验和有限元方法研究了带圆孔复合材料层合板的应力集中,分析了铺层方式对孔边应力集中的影响,对实验和有限元方法得出的结果作了比较.

The test and finite element methods is used to study the stress concentration of the composite laminates with a circle hole ,and analyze the relations between the stress concentration and the angle-ply modes.The results are compared between the test methods and finite element method.
