根据接管区应力应变场的特征,并考虑国际上采用J积分理论的趋势,本文提出了新的“椭圆孔边裂纹板(EHCP)”简化二维模型。本文之(一)就这一模型的有效性进行了研究。
According to the characteristics of the stress-strain field in the take-over zone and considering the international trend of adopting the J-integral theory, a new simplified two-dimensional model of “EHCP” was proposed in this paper. This article (a) studies the validity of this model.
