Consider a panel of aluminum alloy (KIC = 44 MPa m ) that contains internal micro-cracks and surface cracks as long as 0.1 mm in length. What is the tolerable tensile load, in N, to avoid catastrophic failure? The panel is 200 mm in width, 2 mm in thickness. The geometry correction factor is 1.0 for internal cracks, 1.1 for surface cracks.
