复合材料压缩实验时应力分布的有限元计算

Finite Element Analysis of Stress Concentration for Compressive Testing of Composites

碳纤维增强树脂基复合材料(简称CFRP)薄板压缩实验时有三种不同的加载形式。本文对这三种加载形式进行了研究和分析,并用有限元素法计算了这三种加载形式在1—3面内的压应力和层剪应力的分布。

Compression testing for then plate specimens of carbon fiber reinforced composites has three types load-ing.The three loading type are studied and analyzed,and calculated with finite element method for com-pressive stresses and interlaminar shear stresses distribution on 1-3 face.
