| 摘 要： | 采用微裂纹区分段线性应变软化律，并考虑由微裂纹演化而造成的弹性刚度劣化对裂缝扩展的影响，在给定σ－ω软化律的基础上，用应变增量迭代法，数值模拟了混凝土三点弯曲梁的Ｐ－△全曲线。

| Abstract: | In this paper,the strain softening law for the microcrack zone is assumed to be linear in different deformation stages.The degradation of elastic stiffness is considered.When the O-W,softening law is given,using strain increment iteration,the numerical simulation of the P-? complete curve of a three-point bending concrete beam is realized. |
