# Shell Forces & Moments

How to view in-plane and out-of-plane shell forces and moments for a selected load combination.

Click **Analysis Results > Shell Forces, Moments & Stresses > Shell Forces & Moments** to see a table of shell forces and moments. The *Shell Forces and Moments* table appears.

![](https://3750289988-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FlRZtG5Ynp58kYzLHYbR7%2Fuploads%2Fgit-blob-bc3e515c5436fddb1422f2fc9bff370970fc05a4%2FShell%20forces%20and%20moments%20table.jpg?alt=media)

Select the desired Load Combination.

Choose whether the table should display results for the selected entities or for all entities.

Specify the force and moment locations to be at the nodes and/or the center of each shell by clicking **Settings and Tools > Data Options**.

The table reports shears and moments for the desired shells.

The shell forces and moments include:

* Fxx: in-plane normal force in the local x direction
* Fyy: in-plane normal force in the local y direction
* Fxy: in-plane shear force
* Mxx: out-of-plane bending moment on the x face (about the local y axis)
* Myy: out-of-plane bending moment on the y face (about the local x axis)
* Mxy: out-of-plane torsional moment
* Vxx: out-of-plane shear force on the x face
* Vyy: out-of-plane shear force on the y face

The table can be printed with the Print button.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.enercalc.com/e3d-training-manual/analysis/reviewing-the-analysis-results/shell-forces-moments.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
