How to Calculate Critical stress for crack propagation?
Critical stress for crack propagation calculator uses Critical stress=sqrt(2*Young's Modulus*Specific surface energy/(pi*Crack Length)) to calculate the Critical stress, Critical stress for crack propagation is the minimum stress required for propagation of crack in a brittle material. Critical stress and is denoted by σ_{c} symbol.
How to calculate Critical stress for crack propagation using this online calculator? To use this online calculator for Critical stress for crack propagation, enter Young's Modulus (E), Crack Length (a) and Specific surface energy (γ_{s}) and hit the calculate button. Here is how the Critical stress for crack propagation calculation can be explained with given input values -> 43.70194 = sqrt(2*100000000000*0.3/(pi*1E-05)).
