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 ...

Understanding Stresses in Beams
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 ...
When Karl von Terzaghi applied the effective stress principle in the soil mechanics theory, the strength and volumetric behavior of saturated soils could be clearly understood and general constitutive ...
