How do thermally induced microcracks alter microcracking mechanisms in Hong Kong granite
TLDR
In this paper, the authors analyzed the effects of pre-existing thermal microcracks on the microcracking mechanisms of Hong Kong granite under mode I loading, and found that the presence of the thermal micro-cracks aggravates the micro crack damage.About:

Temperature damage regularity of granite based on micro-inhomogeneity
TL;DR: In this paper , the authors used the crystalline rock heterogeneity coefficient H to describe the crystal structure of dry hot granite, and the discrete element software was used to construct the GBM equivalent crystalline model and the thermal temperature field coupling model.

Quasi-static fault growth and shear fracture energy in granite
TL;DR: In this article, the failure process in a brittle granite sample can be stabilized by controlling axial stress to maintain a constant rate of acoustic emission, and the post-failure stress curve can be followed quasi-statically, extending to hours the fault growth process.
