The edge-cracked component shown in the figure below has ay = 640 MPa and Klc = 95 MPam. (Take Y=1.12 for edge crack) 1 cm 10 cm 3 cm (a) Calculate the maximum load the component can withstand. (b) If the component is to be designed with a safety factor of 1.2 against yielding and 2 against fracture, what is the allowable stress? (c) Calculate the maximum crack size so that the component failure is through yielding. (d) Draw the o- a plots for yielding and fracture, indicate the failure surface on the plot. (e) If the component had a center crack of same size rather than an edge crack, what would be the maximum load? (Take Y=1 for a center crack.)
