The image above represents rod toughness. To calculate rod toughness, three essential parameters are needed and these parameters are Short Rod Calibration Constant (A), Maximum Load (Pc) and Short Rod Diameter (B).
The formula for calculating rod toughness:
KIC = APcB-3/2
Where:
KIC = Rod Toughness
A = Short Rod Calibration Constant
Pc = Maximum Load
B = Short Rod Diameter
Let’s solve an example;
Find the rod toughness when the short rod calibration constant is 12, the maximum load is 14 and the short rod diameter is 18.
This implies that;
A = Short Rod Calibration Constant = 12
Pc = Maximum Load = 14
B = Short Rod Diameter = 18
KIC = APcB-3/2
So, KIC = (12)(14)(18)-3/2
KIC = (12)(14)(0.013)
KIC = 2.199
Therefore, the rod toughness is 2.199 J/m³.
