摘要
本文用线弹性断裂力学和虚裂纹模型相结合的方法推导出了三点弯曲梁开裂过程的计算公式,并通过数值计算实现了对实测梁的 P～δ曲线的计算拟合。
A formula of cracking process on the beam with threepoint bending load was inferred by the means of combination Linear elastic fracture mechanics with virtual crack model.This formula has been coincided with the P—δ curve of the actual measured beam through the numerical computation.
