摘要
强度理论是研究复杂应力状态下材料是否破坏的理论,该文总结了古典强度理论以及混凝土和各向同性岩石等两类现代强度理论,将各项同性现代强度理论分为剪应力强度理论、八面体强度理论与主应力强度理论。通过收集国内外已有相关三轴实验数据对各种主要强度理论进行论述、比较与评价,在此基础上对混凝土和各向同性岩石的主应力空间损伤比强度理论进行展望。
Strength theory deals with the failure of materials under complex stress states.Summarizing the classical strength theories and two kinds of modern strength theories of concrete and isotropic rock.Isotropic strength theories include shear stress strength theory,octahedral strength theory,and principal stress strength theory.Various major strength theories were discussed,compared,and evaluated through collecting relevant domestic and foreign triaxial experimental data.Based on previous researches,the principal stress-space strength theories of concrete and isotropic rock were prospected.
