【摘要】 本文根据在ＭＴＳ电液伺服试验系统上完成的不同应变控制加载工况的循环受压砼应力—应变全过程试验及相应声发射检测结果分析了受压砼全过程的声发射特性，然后利用损伤力学的等效应变假定建立了考虑不可逆效应的循环受压砼本构关系，该模型兼容理想弹性损伤本构模型和一般弹塑性本构模型。经比较，本文所建模型与实验结果吻合较好。更多还原

【Abstract】 By detecting the acoustic emission energy rate during the complete process tests ofconcrete under cyclic compression,the complete process acouStic Characteristics were analyzed. Anew constitutive model was proposed based on the equivalent strain hypothesis,which consideringthe effect of irreversible deformation, and it is in a good agreement with the experimental dataunder cyclic compression.更多还原
