A ceramic specimen is being pulled in tension. The specimen contains flaws

A ceramic specimen is being pulled in tension. The specimen contains flaws having a size of 100 m. (a) If the surface energy of the ceramic is 0.9 J/m, what is the fracture stress? Use the Griffith criterion. E = 420 GPa. (b) Using your knowledge of fracture mechanics, estimate the fracture stress if the fracture toughness is 3 MPa m/2. Assume two positions for flaw: in the center and at the edge.
