摘要
研究各向异性纤维复合材料板的断裂问题.首先给出了Ⅰ、Ⅱ混合型,Ⅲ型裂纹尖端的应力与位移公式的极坐标形式.其次将应力与位移代入应变能释放率的基本公式,推出了Ⅰ、Ⅱ混合型,Ⅲ型以及Ⅰ、Ⅱ、Ⅲ混合型裂纹尖端应变能释放率的具体计算公式。
In this paper, the fracture problem for anisotropic fiber composite plate is studied. The polar coordinates forms of stress and displacement are given first.And then,substituting stress and displacement into basic formula of strain energy release rate,computing formula for strain energy release rate of mode III, mixed mode crack tips are direved.
