This article presents the stresses at the center of a Brazilian disk (BD) for transversely isotropic rocks. It is shown that the solution of stresses at the center of an anisotropic disk is a function of the disk radius and the magnitude of applied l

This paper is dedicated to modeling of fuel sloshing dynamics and its effect on the stability and control of the space vehicle. Sloshing due to the liquid movement in the fuel tank of a space vehicle's propulsion system can be effective on the vehicl

This paper presents the results of 124 pure Mode I fracture toughness tests on two types of anisotropic rocks, the metamorphic Grimsel Granite and the sedimentary Mont Terri Opalinus Clay. The results show that Mode I cracks in anisotropic rocks tend

We evaluate the accuracy of three well-known fracture growth theories to predict crack trajectories in anisotropic rocks through comparison with new experimental data. The results of 99 fracture toughness tests on the metamorphic Grimsel Granite unde

This paper presents the mixed-mode I / II stress intensity factors (SIFs) of the through-thickness cracked Brazilian Disk (TCBD) specimen made of an anisotropic rock. We show that the SIFs of an anisotropic TCBD specimen not only depend on the geomet

The conventional semi-circular bend (SCB) test of anisotropic rocks, with symmetric loading, generates a Mixed-Mode I / II crack tip loading when the crack is not aligned with one of the principal material directions. This paper presents a modified S

The double-edge notched Brazilian disk (DNBD) test is used to investigate the failure mechanism of the polymeric material of polymethyl-methacrylate (PMMA) under dominant shear loading. It has previously been shown that DNBD is a simple and efficient
