摘要:An evaluation method of the crack tip reverse plastic zone size (CTRPZS) for the center cracked steel plate under tension-compression cyclic loading is proposed. In this method, the variable quantity of maximum crack opening displacement (VMCOD) is used to study the effect of compressive loads on CTRPZS. In the compressive loading stage, CTRPSZ increases linearly with increasing of the compressive load on basis of the existing CTRPZS after the tensile loading and tensile unloading processes. The maximum CTRPZS can be expressed with respect to VMCOD. This expression is suitable for center cracked finite plates with different materials under tension-compression cyclic loading.
