2. fracture mechanics. a structural component in the form of a wide plate is to be fabricated from a steel alloy that has a plane- strain fracture toughness of 98.9 mpa √ m and a yield strength of 860 mpa . the flaw size resolution limit of the flaw de tection appa ratus is 3.0 mm . if the design stress is one- half the yield strength and the value of y is 1.0, determine whether a critical flaw for this plate is subject to detection.

the critical flaw is subject to detection since this value of ac (16.8 mm) is greater than the 3.0 mm resolution limit.  

Explanation:

This problem asks that we determine whether or not a critical flaw in a wide plate is subject to detection  given the limit of the flaw detection apparatus (3.0 mm), the value of KIc (98.9 MPa m), the design stress (sy/2 in which s y = 860 MPa), and Y = 1.0.

Therefore, the critical flaw is subject to detection since this value of ac (16.8 mm) is greater than the 3.0 mm resolution limit.  

the answer is a)
