Hole with stress concentration factor 2 35 mm W2 35 mm „P to - 300 mm - 350 mm 250 mm
The stress concentration occurs whenever there is an abrupt change in the cross-section of a component or there is any discontinuity in the material. The figure given below shows a flat plate with a hole of diameter d. The plate is fixed at one end and the other end is subjected to a tensile load of P = 44 kN due to which there is a change in length of 0.4 mm. The thickness of the plate is 11.5 mm. The maximum stress developed in the flat plate is 228 MPa. Take Young's modulus(E) = 210 GPa and theoretical stress concentration factor =2,
Calculate the following values:
i) Width of the plate (W2) in mm (
ii) Nominal Stress in MPa (
iii) Diameter of the hole (d) in mm
