In this video we explore bending and shear stresses in beams. A bending moment is the resultant of bending stresses, which are normal stresses acting perpendicular to the beam cross-section. We can ...

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 ...

Principal stresses are defined as the maximum and minimum normal stresses in a plane. Principal stresses are perpendicular to each other and oriented such that shear stresses are zero. For 3D stress ...
