摘要
提出分析中心裂纹板剪切断裂的断裂过程区Ｄ－Ｂ模型的叠加原理，考虑了压剪断裂的摩擦阻力和体现有限板宽影响的载荷修正，以非常简便的方法推导出计算断裂过程区长度和位移的公式．
For the shear fracture process zone in a center cracked finite-width strip based on Dugdale- Barrenblatt model, the formulas for length and dis- placement of the fracture process zone are derived by using the superposition principle and load modification approach. The effect of shear friction and finite with of the strip is considered in a very simple and effective way.
