WebSo, stress concentration is not desirable as the holes and sharp edges will become the weakest part of the entire work piece. We can calculate the strength of the work piece under stress concentration by using the relation below-. Kt = σmax/σ. Image: Stress concentration at sharp corners. Image credits : Wikipedia. Web(a) The maximum shear stress may be calculated from equation (7.3) or it may simply be read from the Mohr circle. Clearly τ max = σ1 - σ3 2 = 15 kN/m 2 The points of maximum shear stress are represented by C and D. Therefore the planes on which these stresses act are parallel to lines OP C and O P D respectively. As shown
