How To Define Moment In ANSYS Mechanical(Illustrated Expression)

In this article we will show you how to define moment to a geometric feature in ANSYS Mechanical. In mechanical systems, moment have very important place. Calculation and application of moments to structural systems can affect the behaviour of the part or engineering system. So defining moments in a correct way is very important thing for enginering systems. Also Moment is a boundry condition in finite element methods and you  know that the boundry conditions in finite element methods is very important parameter.

In this text you will learn about how to apply moments to parts in ANSYS Mechanical in effective way.

How To Define Moment On A Part In ANSYS Mechanical?

Click on Moment.

To apply a moment to a part in ANSYS Mechanical, you need to right click on analysis system(Static Structural in this example). After that you need to hover your mouse on Insert tab as shown by red arrow then click on Moment command as shown in red box above in ANSYS Mechanical.

Select the geometry in ANSYS Mechanical.

You can select the geometry to apply moment on it as shown by red arrow above. Click on geometrşc feature or features then click on Apply button in Geometry section as shown by red arrow in ANSYS Mechanical.

Select a method for moment

You can define your moment value as components or as vector as shown in red box above in ANSYS Mechanical. If you select Components, you need to enter your moment value as X, Y and Z coordinates. Also you can add your moment by selecting vector that you eenter a moment value and define a vector from the geometry.

Entered moment values.

For example we defined moment as shown in red box in X, Y and Z coordinates, and the resultant of these moment values as shown by red arrow above in ANSYS Mechanical.

Moment behaviour selection.

Also you can define moment behavior such as Rigid, Deformable, Coupled, or Beam. If you select the Beam, you need to specify a Beam diameter.

The moment application in ANSYS Mechanical is like that.
