Question 58
MTNAT2 marksNeeds review
For a component fabricated from an alloy A with plane strain fracture toughness,
MPa m
, 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
MPa m
, 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).Log in to check the answer
