Bending Stress Calculator

Calculate nominal elastic bending stress from moment and section modulus.

Moment and section

Elastic bending result

Maximum bending stress100 MPa

At the extreme fibre

Section modulus
10,000 mm³
Bending stress
100 MPa

This simple elastic relation excludes stress concentrations, lateral buckling, shear, deflection, fatigue and combined loading. Use the section modulus about the actual bending axis.
