The image above represents maximum allowable flow length. To calculate maximum allowable flow length, three essential parameters are needed and these parameters are Fracture Toughness (KIC), Applied Load Constant (Y) and Stress (σ).
The formula for calculating maximum allowable flow length:
ac = 1/π(KIC/σY)²
Where:
ac = Maximum Allowable Flow Length
KICÂ = Fracture Toughness
σ = Stress
Y = Applied Load Constant
Let’s solve an example;
Find the maximum allowable flow length when the fracture toughness is 10, the stress is 2 and the applied load constant is 5.
This implies that;
KIC = Fracture Toughness = 10
σ = Stress = 2
Y = Applied Load Constant = 5
ac = 1/π(KIC/σY)²
ac = 1/π(10/(5)(2))²
That is, ac = 1/π(10/(10))²
ac = 1/π(1)²
ac = 1/Ï€(1)
So, ac = (0.318)(1)
ac = 0.318
Therefore, the maximum allowable flow length is 0.318 m.
