WebSimple 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 stress state leading to expansion; … Webto resist the growth of shear deformation is called viscosity. The form of the relation between shear stress and rate of strain depends on a fluid, and most common fluids obey Newton’s law of viscosity, which states that the shear stress is proportional to the strain rate: τ = µ dγ dt. Such fluids are called Newtonianfluids. The ...
