3.2 A steel tension bar 8-mm thick and 50-mm wide with an initial single- edge crack of 10-mm long is subjected to an uniaxial stress = 140 MPa. a) Determine the stress intensity factor K₁. Is the crack stable? b) Determine the critical crack size, and c) determine the critical load. Data: Kic = 60 MPa√m. [Solution: a) 34 MPa, b) 31.1 mm, and c) 98.84 kN]. 3.2 A steel tension bar 8-mm thick and 50-mm wide with an initial single- edge crack of 10-mm long is subjected to an uniaxial stress = 140 MPa. a) Determine the stress intensity factor K₁.
