An inspection is carried out on a 1 m wide large plate in a factory made from aluminium alloy. A 48 mm wide elliptical hole is found at the centre of the plate, with the notch root radius of 6 mm. Engineers judge that if the plate can withstand a force of 240 kN applied parallel to its length without yielding anywhere, it is still acceptable in service. Note that the value of the stress concentration factor of this component is given by: KT = 1+2 (1 where a is the major semi-axis and p is the notch root radius. If the yield strength of the aluminium alloy is 300 MPa, what is the minimum allowable thickness of the plate if it can still be used in service? In addition, if the applied load continues to increase further, what is the likely mode of fracture? An inspection is carried out on a 1 m wide large plate in a factory made from aluminium alloy.
