A water pipe is designed with internal and external radii of 147.5 and 167.6 mm, respectively. The material properties are of 40 MPa, Kic=3.1 MPavm. The largest defects present after fabrication are 100 um flaws at the outer surface. The K can be found in lecture note 3_2 longer example, K= о⁹√(ла)/Q assuming a/t and a/c are very small and ignorable. = (a) Before being put into service the pipe undergoes a pressurization "proof' test. Will the pipe first fail by yield or fracture during such a test? Determine the pressure to cause "failure". (b) One of the pipe suppliers had problems with their processing conditions and shipped pipe with Kc =1.5 MPa√m. Calculate the maximum pressure for this pipe if the largest flaw remains 100µm but present at the inner surface.
