摘要
对岩石在单轴受力状态下的损伤扩展进行CT扫描,分别利用CT扫描和Lemaitre等效应变假设计算其损伤变量。损伤本构关系分析表明,Lemaitre等效应变假设采用不同形式损伤变量时,既有形式上的差异,又有其内在的联系。
The CT scanning of rock under uniaxial stress is researched in this paper. Damage variables are calculated using CT scanning and Lemaitre's equivalent strain hypothesis respectively. The analysis of damage constitutive relation shows that different damage variables have both the formal discrepancy and the intrinsic connection between them.
