Asharp through crack in a relatively large thick plate is 25 mm long. the plate is subjected to uniform uniaxial stress distributed along two opposite edges of the plate and acting perpendicular to the crack faces. the plate material’s mode i fracture toughness is reported to be 50 mpa-m1/2. at what stress value would you expect the crack to propagate rapidly, to complete fracture?
a. 78mpa
b. 6mpa
c.252 mpa
