WebMay 30, 2024 · The meaning of the statement that the stress tensor is not a vector refers uniquely to the fact that it is neither a direction nor a force. However, the set of all possible stress tensors can be equipped with a sum and a scalar multiplication obeying all the axioms of a vector space. WebLike force and velocity, stress is a vector quantity. The stress vector can be resolved into a component perpendicular to the surface (the normal stress), and a component parallel to the surface (the tangential, or shear stress) The stress field about any point in the body may be isotropic (also called hydrostatic) or anisotropic (non-hydrostatic).

WebScalar is a quantity having only magnitude. A vector is a quantity that has magnitude and direction both. Tensor is a quantity having magnitude, direction, and plane too. Stress is a tensor as it obeys the coordinate transformation law. Stresses are not vectors because they do not combine according to the parallelogram law of addition. WebStress is generally defined as force per unit area. When forces pull on an object and cause its elongation, like the stretching of an elastic band, we call such stress a tensile stress. …
