What is the magnitude of the maximum stress that exists at the tip of an internal crackhaving a radius of curvature of 1.9 x 10" mm and a crack length of 3.8 x 10 mm when atensile stress of 140 MPa is applied?4.5. A ceramic matrix composite contains internal flaws as large as 0.001 cm in length. Theplane strain fracture toughness of the composite is 45 and the tensile strength is 550 MPa.Will the flaw cause the composite to fail before the tensile strength is reached? Assumethat Y 1A cylindrical rod 500 mm long, having a diameter of 12.7 mm, is to be subjected to atensile load. If the rod is to experience neither plastic deformation nor an elongation ofmore than 1.3 mm. when the applied load is 29,000 N, which of the four met ls or alloyslisted below are possible cardidates?
