WitrynaSimple stresses. In some situations, the stress within an object can be described by a single number, or by a single vector (a number and a direction). Three such simple stress situations are the uniaxial normal stress, the simple shear stress, and the isotropic normal stress.. Uniaxial normal stress. Tensile stress (or tension) is the … The state of stress at a point in the body is then defined by all the stress vectors T associated with all planes (infinite in number) that pass through that point.

It arises from the shear force, the component of force vector parallel to the material cross section. Normal stress, on the other hand, arises from the force vector component perpendicular to the material cross section on which it acts. ronald m layton
