toughness of 25 MPa√𝑚. It has been determined that fracture results
at a stress of 270 MPa when the maximum (or critical) internal
crack length is 1.5 mm. For this same component and alloy, will
fracture occur at a stress level of 400 MPa when the maximum
internal crack length is 1.0 mm? Why or why not? Note: the value
of 𝑌 ≠ 1.
