The image of brittle material critical stress is represented below. To calculate brittle material critical stress, three essential parameters are needed and these parameters are Modulus of Elasticity (E), Specific Surface Energy (γs), and Length of Crack on Surface (a).
The formula for calculating brittle material critical stress:
σc = (2Eγs/πa)0.5
Where:
σc = Brittle Material Critical Stress
E = Modulus of Elasticity
γs = Specific Surface Energy
a = Length of Crack on Surface
Given an example;
Find the brittle material critical stress when the modulus of elasticity is 10, the specific surface energy is 14 and the length of crack on surface is 8.
This implies that;
E = Modulus of Elasticity = 10
γs = Specific Surface Energy = 14
a = Length of Crack on Surface = 8
σc = (2Eγs/πa)0.5
σc = (2(10)(14)/π(8))0.5
That is, σc = (280/25.132)0.5
σc = (11.140)0.5
σc = 3.337
Therefore, the brittle material critical stress is 3.337 Pa.
