WebTensile stress is the stress state caused by an applied load that tends to elongate the material along the axis of the applied load, ... Many machine parts fail when subjected to a non-steady and continuously varying loads even though the developed stresses are below the yield point. Such failures are called fatigue failure. WebDec 18, 2024 · When an object is loaded at its boundary, the stress components are the normal stress, shear stress, and displacements. Normal stress is the force per unit area in the direction of a surface normal. Shear stress is the force per unit area in the direction perpendicular to the surface normal.
