Effect of the intermediate principal stress on 3-D crack growth

open access: yesEngineering Fracture Mechanics, 2018
Abstract An experimental and numerical investigation of 3-D crack growth in biaxial compression is presented. We tested a series of transparent casting resin samples, each with a single initial penny-shape crack at the sample centre. We applied biaxial compression with different ratios ( σ x / σ y ) between the lateral (the intermediate

Influence of the Intermediate Principal Stress on Sandstone Failure

Rock Mechanics and Rock Engineering, 2019
This paper reports the results of fracture testing of sandstone under constant minor principal stress (20 MPa) and various intermediate principal stresses. The results show that when the minor principal stress is constant, as the intermediate principal stress increases, the ratio of the octahedral shear stress (τoct) to the octahedral normal stress ...
