The stress intensity factor for a partial-through thickness crack is given by where a is the length of of crack through a wall thickness t. If the crack is 10 mmdeep in a wall 20 mm thick determine whether the wall will support a stress of 190MPa if it is made from steel with fracture toughness of 30 MPA m1/2.
