For a component fabricated from an alloy A with plane strain fracture toughness, KIC=50 MPa m1/2, fracture was observed to take place at a crack length of 0.4 mm at a tensile service stress of σ.
If the same component is instead fabricated from alloy B with KIC=75 MPa m1/2, the crack length at which a similar crack geometry will result in fracture (under identical tensile service stress of σ) is ______ mm (rounded off to one decimal place).
If the same component is instead fabricated from alloy B with KIC=75 MPa m1/2, the crack length at which a similar crack geometry will result in fracture (under identical tensile service stress of σ) is ______ mm (rounded off to one decimal place).
