摘要
本文从材料构成的基本物理概念出发,简要说明了材料的屈服是受三向应力、荷载历史、外界环境等的作用,材料内部紧密相连的质点间的距离增大到某临界值K_0所致。由此提出了最大分离位移(MAXSD)屈服准则。并与岩石真三轴压缩试验和混凝土双轴试验结果,以及莫尔-库仑等屈服准则进行了比较,证实了其合理性和适用性。
The materials be yielded due to its particles separated to a critical value K0 which is effected by the factors of three-dimensional stress, loading history, external environment etc. From the fundamental physical concepts of the materials composition, the yield criterion of the maximun separate displacement (MAXSD) is put forward. The MAXSP is compared with the result of the rock true triaxial compression test and that of the concrete twin-shaft, and is compared with Mohr-Coulomb's yield criterion to prove its reasonable and suitabile for the rock and concrete brittle materials.
