Failure mode of compression test
WebMar 10, 2024 · The uniaxial compression of rock specimens with horizontal non-penetrating surface fissures produced three-dimensional failure modes, and the depth of surface fissures changed the failure mode of the specimens under uniaxial compression. As the crack depth increased, the failure mode of the specimen changed from tensile failure to … WebConsider first the fiber failure mode in axial tension discussed in Section 2.8.4.5. The essential feature of this failure mode is the local load sharing from one failed fiber to its …
