• ### Modulus of rupture calculationCalculate Flexure

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
