Effect of Native Fissures on the Mechanical Behaviour of Rock under Uniaxial Compression
Original scientific paper Rock generally contains various micro-cracks, fissures, pores, joints, and other defects. These defects affect the mechanical properties of rock. In order to clarify the influence of native fissures on rock deformation and failure modes, a laboratory study was carried out using the fissured dolomite, and acoustic wave velocity measurement and natural water absorption t...
متن کاملNumerical Studies on the Failure Process of Heterogeneous Brittle Rocks or Rock-Like Materials under Uniaxial Compression
In rocks or rock-like materials, the constituents, e.g. quartz, calcite and biotite, as well as the microdefects have considerably different mechanical properties that make such materials heterogeneous at different degrees. The failure of materials subjected to external loads is a cracking process accompanied with stress redistribution due to material heterogeneity. However, the latter cannot b...
متن کاملBuckling and failure characteristics of slender web I-column girders under interactive compression and shear
Geometric and material nonlinear behavior of slender webs in I-column girders having stocky flanges under the action of combined lateral and axial loads is investigated. Interaction curves corresponding to the application of compressive and shear loads at buckling and ultimate stages for both web plates and column sections are plotted. In addition, the effects of flange and web slenderness rati...
متن کاملDetermination of Damage Constitutive Behavior for Rock Salt Under Uniaxial Compression Condition with Acoustic Emission
The mechanical characteristics of rock salt have an important influence on the safety of the salt cavity. The acoustic emission (AE) technique was used to analyze the generation of microcracks in rock salt under uniaxial compression condition. By monitoring acoustic emission in whole process of stress strain curve under uniaxial compression test, the damage characteristic of rock salt is obtain...
