TL;DR: In this article, the results of a series of tests conducted to study the mode I fracture toughness of a sedimentary soft rock (Guiting Limestone) were presented. But the results showed that there was a noticeable difference between the sets of test data and that the fracture resistance was significantly dependent on the geometry and loading conditions of the test specimen.

TL;DR: In this paper, a new and more accurate approach is suggested for predicting mode II fracture toughness of rocks using the maximum tangential stress (MTS) criterion, which takes into account the first three terms of William's series expansion for elastic stresses near the crack tip.

TL;DR: In this paper, the results of a semi-solid tensile test conducted in situ using X-ray microtomography are compared with the predictions of a coupled hydromechanical granular model in order to both validate the predictions and explain the experimental observations.

TL;DR: In this paper, a 3D coupled hydromechanical granular model was developed and validated to directly predict hot tear formation and stress strain behavior in metallic alloys during solidification.

TL;DR: In this paper, a semi-circular specimen containing a vertical edge crack was used to assess mode I, mode II, and mixed mode fracture toughness of a marble rock, which was subjected to three-point bending while the bottom supports were placed asymmetrically with respect to the crack position.
