From the question we are told that:
Plane strain fracture toughness of
Y value
Stress level of
Generally the equation for length of a surface crack is mathematically given by
Therefore
in mm
A three-point flexure test is conducted on a cylindrical specimen of aluminum oxide. The specimen radius is 5.0 mm and the dista
nce between the two supportsis 15.0 mm. If the specimen breaks when the applied force is 7500 N and the center deflection is 0.01 mm, what are the elastic modulus andthe flexural strength of the material?
