Modulus of rupture calculator - Calculate Flexure / Torsional Strength

Modulus of Rupture is an ultimate strength determined in a flexure or torsion test. In a flexure bending test, it is the maximum fiber stress at failure. In a torsion test, it is the maximum shear stress in the extreme fiber of a circular member at failure. Alternate terms are flexural bending strength and Torsional Strength.

Bending Test Calculation:
Breaking Load = pounds
Average distance = Inches
Average Breadth = Inches
Average Depth = Inches
Modulus of Rupture = Pound per Square Inch

Formula Used: M = ( 3 * P * L ) / ( 2 * b * d2 ) Where, M = Modulus Of Rupture P = Breaking Load L = Distance Between Knife Edges on which the Sample is Supported b = Average Specimen Breadth d = Average Specimen Depth In general Modulus of Rupture is used in both flexure bending and torsional test.
