The image above represents crack opening displacement. To calculate crack opening displacement, three essential parameters are needed and these parameters are Fracture Toughness of Material (K), Elastic Modulus (E) and Yield Strength (σys).
The formula for calculating crack opening displacement:
d = K² / 2Eσys
Where:
d = Crack Opening Displacement (E)
K = Fracture Toughness of Material
E = Elastic Modulus
σys = Yield Strength
Let’s solve an example;
Find the crack opening displacement when the fracture toughness of material is 21, the elastic modulus is 11 and the yield strength is 7.
This implies that;
K = Fracture Toughness of Material = 21
E = Elastic Modulus = 11
σys = Yield Strength = 7
d = K² / 2Eσys
So, d = (21)² / 2(11)(7)
d = (441) / (154)
d = 2.86
Therefore, the crack opening displacement is 2.86 m.
