Enter the bending moment, vertical distance from the neutral axis, and the moment of inertia around the neutral axis into the calculator to determine the bending stress.

## Bending Stress Formula

The following formula is used to calculate the bending stress of a typical geometry.

**σ** = M * y / I

- Where M is the bending moment
- y is the vertical distance from the neutral axis
- I is the moment of inertia about the neutral axis

## Bending Stress Definition

A bending stress is a stress of along the the length of an object that arises from a bending force.

## Bending Stress Example

How to calculate bending stress

**First, determine the bending moment**Calculate or measure the bending moment of the object.

**Next, determine the distance from the neutral axis.**At the point being analyzed, measure the vertical distance from the axis.

**Next, determine the moment of inertia.**Calculate or measure the moment of inertia about the neutral axis.

**Finally, calculate the bending stress.**Calculate the total bending stress using the formula above.

## FAQ

**What is a bending stress?**

A bending stress is particular type of stress that occurs in an object when it is subject to a large enough force that causes the object to bend and fatigue.

**What type of force causes bending stress?**

Bending stress is caused by tensile forces and loads.
