— This paper reports on a three‐dimensional numerical prediction that involves continuum damage theory for the deformation of centre cracked panels under uniaxial and biaxial tensile loading. The predicted differences of crack tip blunting movement, crack tunnelling behaviour and the changing shape of the plane ahead of the crack tip for the two loadings are close to those observed in tests. The material parameters that encapsulate the damage response of the A533 B class 1 steel tested, were selected from a detailed parametric study on laboratory crack‐growth resistance tests on the material.
