CRACKING BEHAVIOR AND MECHANICAL ANALYSIS ON DUPLEX STRUCTURE UNDER CYCLIC LOADING

WANG Zhaoxia CHAI Donglang LIU Jinghua Xi′an Jiaotong University , Xi′an , China

金属学报(英文版)

On the basis of stress-strain analysis under cyclic loading,the mechanism,origin and cyclic number of microcraek nucleation of duplex structure materials,saying ferrite plus martensite, have been experimentally studied and calculated.Both results are in fair mutual agreement. The morphology,distribution,size and relative quantities of the constitutional phase,especial ly strengthening phase,as well as the stress-strain distribution and variation in micro-region are directly influential in the origin of microcracks in duplex structure materials.

本文依据动载下应力应变分析模型,采用两种形态的双相组织(F+M)进行试验和计算。裂纹优先在岛状组织基体内产生、条状组织中强化相优先启裂,以及微裂纹的萌生周期等试验结果与计算基本吻合。
