Question:

A thin large sheet of maraging steel has a through-thickness internal crack, which is 4.0 mm long and orientated perpendicular to the stressed direction. For this steel, E can be taken as 200 GPa, the energy of the fracture surface is 2.0 J/m2 , and the work of plastic deformation of each crack tip is 2.0 104 J/m2 . Determine the critical stress for brittle fracture
