Static Structural Analysis In ANSYS®

This article can be a good reference to make static structural analyses in ANSYS® Mechanical. You can find out information about static structural analysis in ANSYS® that you can assess whether the static structural analysis in ANSYS® is proper for your engineering system.

What Is Static Structural Analysis?

As you understand from its name, in static structural analyses, static conditions exist. In static structural analyses in ANSYS®, loads, stresses, strains, and other physical loads like them are assumed to not changing extremely with the changing time. So unlike dynamic analyses, damping and inertia effects are negligible in static structural analyses in ANSYS® Mechanical.

We want to remind you that, gravitational effects and rotational forces are examples of static forces applied to bodies.

How To Make Static Structural Analyses In ANSYS® Mechanical?

First of all, take a static structural analysis from the toolbox section to the project schematic by dragging it with your mouse in ANSYS® Workbench.

Then, you need to have a proper geometry to define it in the ANSYS® Workbench environment. We recommend that take your geometries in .step or .igs forms into ANSYS® Workbench. You can import your geometry from the geometry section on Static Structural analysis.

After importing your geometry inside ANSYS® Workbench, double click on ‘Engineering Data’ to define materials for your parts. There are vast materials that are available in ANSYS® Workbench and you can select one of them from the ‘Engineering Data’ section.

Or you can also create your own materials in ANSYS® Workbenchto use them in static structural analyses.

After selecting your materials and importing your geometries inside ANSYS® Workbench, double click on the ‘Model’ tab to open the Mechanical interface to build your static structural analysis.

Once you entered into the ANSYS® Mechanical, your separate geometry parts are shown beneath the ‘Geometry’ section. You can select your material as shown above for each part in ANSYS® Mechanical.

As you see above, there are a bunch of options for your geometries and parts. You need to define optimum stiffness behaviors, coordinate systems, nonlinear effects, and thermal strain effects. Selecting them properly is very important in terms of solution time and computational source in ANSYS® Mechanical.

After making required settings for geometries and parts, create amesh structure. Proper mesh structures are very important for static structural analyses to obtain correct and near-real results.

ANSYS® Mesher provides a vast of options for obtaining optimum mesh structures for your analyses. You can mesh your structures by using these meshing options in ANSYS® Mechanical.

After obtaining mesh structure in ANSYS® Mechanical, create required connections between your parts to obtain the required system or mechanisms, and define the required boundary conditions such asloadsand supports.

And define what you want to calculate or see in your engineering system by using static structural analysis in ANSYS® Mechanical. As you see above, you can select solution options to see in your static structural analyses in ANSYS®.

Click on ‘Solve’ to obtain solutions for your system.

Important Points To Remember For Static Structural Analysis In ANSYS®

If you are not expecting non-linear behaviors from your system, de-selecting the non-linear option in the static structural analysis will save from computational time and source in a very good way.

Also if you defined your parts as ‘rigid’, you can only add these external loads to your part; Acceleration androtational velocity.

It will be very good if you optimize your mesh more finely at the sections of your geometry where stress, strain, and other deformations are expected. Also, you need to make your mesh finer in your connection sections to obtain realistic results from your analyses.
