If the surface energy of a magnesium oxide - nickel oxide (MgO-NiO) solid solution is 1.23 J/m2 and its elastic modulus is 208 GPa, what is the maximum length of an internal elliptical flaw, in mm, if the ceramic part must survive an applied tensile stress of 97 MPa normal to this elliptical flaw
Answers: 2
where l is the maximum length of elliptical flow, E is the modulus of elasticity, r is the surface energy of magnesium oxide and nickel, 
is the tensile stress.
