Tensile strain is fractional increase in length which is represented by formula = + (/0) Tensile strain = increase in length/ original length. Just Now The maximum tensile stress value at trailing edge is substantial and it can initiate surface cracks that can propagate, leading to fatigue wear and pitting. All of the rest of the deformation to failure occurs at this point as the stress is concentrated in this area of reduced cross section. V = shear force in the cross section (as obtained from the shear force diagram) Q = the first moment of area of the area above the plane upon which the desired shear stress is to be calculated Q. What is the formula for stress and strain? The maximum shear stress theory is also called as Tresca theory of failure. When external forces act upon a material they produce internal stresses within it which cause deformation. In some cases, the material may be able to withstand a certain amount of compressive stress before it fails. Hence the conditions for the failure in three dimensional force are, `\frac{\sigma _{1}-\sigma _{2}}{2}\leq \frac{\sigma _{y}}{2}`, `\frac{\sigma _{2}-\sigma _{3}}{2}\leq \frac{\sigma _{y}}{2}`, `\frac{\sigma _{1}-\sigma _{3}}{2}\leq \frac{\sigma _{y}}{2}`, `| \sigma _{1}-\sigma _{2} |\leq \sigma _{y}`, `| \sigma _{2}-\sigma _{3} |\leq \sigma _{y}`, `| \sigma _{1}-\sigma _{3} |\leq \sigma _{y}`, Where, `\sigma_{1}, \sigma_{2}, \sigma_{3}` are the principal stresses.
