Bending Stress Calculator Of Bending Moments

The effect of the uniform load is considered because the bending moment effect it. To calculate the bending stress, you need to know the total bending moment acting on the point of interest. 

Here, we explain the calculation of normal stresses that occurred at the cross-sections of structures because of the bending moment effect. You can use the calculations prepared for you to calculate your calculations easily and fastly. 

Normal Stresses Due To Bending Moment Calculator

How To Use Bending Stress Calculator Of Bending Moments?

The use of the calculator above is very simple. You just need to enter the required values; bending moment value on the point where the calculations are done, the moment of inertia of the cross-section(you can use this calculator to calculate the moment of inertia for your certain cross-section) of the structural member where calculations are done, the distance of the point of the cross-section where calculation will be made, from the neutral axis of the cross-section. 

Click on the ‘Calculate’ button to see the normal stress value on that point. If you want to make additional calculations, click on the ‘Reset’ button to make a new calculation. 

How To Calculate The Bending Stress Due To The Bending Moments?

It is very basic. You just need to specify the parameters correctly. 

First of all, you need to calculate the bending moment correctly. Bending moments can occur due to the different loading conditions such as uniform loads, singular loads, multiple loads. You need to obtain the bending moment diagram to see the total bending moment at the point of calculation. 

Cross-section of the structural member that you are making your calculations must be constant. Otherwise, calculations will be very different complex. Calculate the area moment of inertia of the cross-section around the neutral axis. 

In this cross-section, you may need a bending stress value on a point that has a distance from the neutral axis. Specify this distance which is appeared as ‘y’ in the formula. 

If you make the calculation, you will have the total bending moment stress on that point.

Take Care About Your Units!

While you are making your calculations, you need to use proper sets of units both for forces, moments, and lengths. All the units must be consistent in your parameters. You can use this calculator with your unit set both in SI and imperial. You can use the MB-Unit Converter tool to make conversions between your units!
