Question

Tutorial 3 A long steel plate has a thickness of 30 mm and a width of 300 mm. On the basis of the inspection technique employed, an initial edge crack of length 8.5 mm is assumed to exist as shown. The plate is subjected to a remotely applied tensile stress which varies cyclically due to 1.8 MN and 2.7 MN tensile variable loading. Determine the stress intensity factor and examine the implications of the crack as relates to the tensile stress. Take $sigma_y$=350 MN/m$^2$
