an aircraft component is subjected to axial loading. It has a rectangular cross - section with a width of 250 mm and a thickness of 25 mm. The component is made of aluminum 7075, which has a fracture toughness of 20 MPa - m 1/2 and a yield strength of 500 MPa. During an inspection, a small edge surf ace crack with a length a = 2 mm was detected. If the component is put into service, will it fail first by fracture or strength ? At what load?

A PMMA plate with a 25 mm (width) x 6.5 mm (thickness) cross-section has a contained crack of length 2c = 0.5 mm in the center of the specimen. If the applied load (along the 2 length direction) is 1000 N, calculate the stress intensity factor. If the fracture toughness of PMMA, K1c = 1.15 MPa.m1/2, at what load (in N) does the crack propagate?
