- Calculation of normal and shear stress on a planeFrequently it is necessary to calculate the normal and the shear stress on an arbitrary plane (with unit normal vector n) that crosses a rigid body in equilibrium. Faults or cracks that cross the rock mass and may lead to rock failure are cases that...
- Transformation of a stress tensor to a new coordinate systemThe transformation (rotation) of a stress tensor into a new coordinate system is a common problem in rock mechanics and in continuum mechanics in general. In this article we will present the necessary equations and an example case. Consider a rigid b...
