A new study uses shear tests and seepage-stress analysis in north China's Liushagang formation to create a model that predicts collapsing pressure and avoids costly drilling delays in hard, brittle ...

Emily Brodsky, professor of Earth and planetary sciences at UC Santa Cruz, has received a $1.1 million grant from the U.S. Department of Energy to study the shear strength of rocks in the Earth’s ...

Dilatants are a class of non-Newtonian fluids characterized by their ability to transition from a fluid state to a near-solid state under shear stress due to a high concentration of solid particles ...

Jointing is a basic function of engineering. For example, bolting two parts together can involve material properties and loading forces. Here, we will focus on preloading, shear and tear-out in a ...

Acoustic time and density have a poor relation with brittleness while elasticity has a good linear correlation with brittleness. Variable compressive strength causes irregular brittleness distribution ...
