Using the maximum distortional energy theory and the stress concentration figures given in section 4.12, find the maximum diameter of the radial hole (d) for a safety factor of n = 1.8. The torsion applied to the shaft is T = 400 Nm, the diameter of the shaft is D = 30 mm and the yield strength of the material is Sy = 460 MPa. Based on the stress concentration figure, assume an initial K₁ value and then revise your solution once you have determined an initial d. T T CS ESC

Create a 2D contour plot to allow the performance of the structure to be assessed against the maximum distortion energy (von Mises) criteria. Comment on the results. You can do this by plotting a contour of the von-mises stress and then normalising the result against the yield stress. This will produce a contour plot of the failure index. This index represents the ratio of the von-mises stress to the yield stress of the material.
