**Unformatted text preview: **Plot the following graphs: (i) stress concentration factor vs. log N ; (ii) maximum von Mises stress vs. log N ; (iii) u A vs. log N , where u A is the displacement in the loading direction at Point A with respect to the hole center. Compare your stress concentration factors with the theoretical value. What is the factor of safety for the bracket according to von Mises yield criterion? Yield stress of aluminum=280 MPa. b) Repeat ( a ) using quadrilateral elements. Your report should contain: (I) brief description of procedures used; (II) all figures and plots neatly and clearly labeled; (III) Discussion and conclusions; and (IV) References. A x y...
