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
Bending stress is stress along 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.
Bending stress is a 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.
Bending stress is caused by tensile forces and loads.
