Static Structural Analysis In ANSYS

blank

This article can be a good reference to make static structural analyses in ANSYS Mechanical. You can find out informations about static structural analysis in ANSYS that you can assess whether 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 as 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 the examples of static forces applied on bodies.

How To Make Static Structural Analyses In ANSYS Mechanical?

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

Drag ‘Static Structural’ from toolbox into project schematic in ANSYS Workbench.

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

Double click on ‘Engineering Data’ to select the materials.

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

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

Download And Install ANSYS R19!

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

Select your materials in ANSYS Mechanical.

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 parts in ANSYS Mechanical.

Make adjustments for each parts.

As you see above, there are 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 ofsolution time and computational source in ANSYS Mechanical.

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

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

Insert required loads for static structural analysis.

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

Define solution results that you want for static structural analysis.

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 in for your system.

Important Points To Remember For Static Structural Analysis In ANSYS

If you are not expecting non-linear behaviours from your system, de-selecting non-linear option in 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 and rotational velocity.

It will be very good if you optimize your mesh in finer way 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.

These are the general information about static structural analysis in ANSYS Mechanical.
