Crack tip fields in anisotropic planes: a review

Majid R. Ayatollahi et al.

Summary: This paper reviews crack tip asymptotic fields in generic plane anisotropic media, categorizing about 400 studies on the determination of crack tip parameters from analytical, numerical, and experimental perspectives. Various methodologies over the past six decades have been explored to determine crack tip parameters in anisotropic materials. Furthermore, the influence of higher order coefficients in the crack tip stress field is demonstrated through a representative example in the literature.

Effects of stress path on brittle failure of sandstone: Difference in crack growth between tri-axial compression and extension conditions

Kamran Panaghi et al.

Summary: This study investigated the strength performance of rocks under different conditions through a series of tri-axial tests, finding that the compressive strength of the rock was higher in tri-axial extension tests. Additionally, the study focused on the influence of crack orientation on crack growth.
