h1. Pre-Analysis & Start-Up

h3. Pre-Analysis

There are three difference theories for finding the solution for the bending of a curved beam. There is elasticity theory

$$
(\frac{4M}{tb^2N}) [( 1 - \frac{a^2}{b^2}ln(\frac{r}{a}) - (1 - \frac{a^2}{b^2})ln(\frac{b}{a})]
$$

h3. ANSYS Simulation

Now, let's load the problem into ANSYS and see how a computer simulation will compare. First, start by [downloading the files here|^Curved Beam Simulation Files.zip]
The zip file should contain the following contents:
- Curved Beam Solution_files folder
- Curved Beam Solution.wbpj

Please make sure to extract both of these files from the zip folder, the program will not work otherwise. (Note: The solution was created using ANSYS workbench 12.1 release, there may be compatibility issues when attempting to open with other versions).

2. Double click "Curved Beam Solution.wbpj" - This should automatically open ANSYS workbench (you have to twiddle your thumbs a bit before it opens up). You will be presented with the ANSYS solution.

A tick mark against each step indicates that that step has been completed.

3. To look at the results, double click on "Results"  - This should bring up a new window (again you have to twiddle your thumbs a bit before it opens up).

4. On the left-hand side there should be an "Outline" toolbar. Look for "Solution (A6)".

We'll investigate the items listed under Solution in the next step in this tutorial.
