App description

Fracture modulus calculator

Enter the value, click on "Calculate" and the result will be displayed.

Calculation formula

\(M=\frac {3×P×L}{2×b×d^2}\)

• M = modulus of rupture / pounds per square inch
• P = breaking load / pound
• L = distance between the edges of the specimen / inch
• b = average width of the sample / inch
• d = average depth of the sample / inch

Usage example

Input data: 10 lbs at break;

average distance 2 inches;

average width 2 inches;

average depth 2 inches;

click "Calculate" to display the results.

Output: Fracture modulus is 3.75 pound/square inch.
