Pre-Analysis & Start-Up

Pre-Analysis

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

Unknown macro: {latex}

$$
\sigma_r = (\frac

Unknown macro: {4M}
Unknown macro: {tb^2N}

) [( 1 - \frac

Unknown macro: {a^2}
Unknown macro: {b^2}

\ln(\frac

Unknown macro: {r}
Unknown macro: {a}

) - (1 - \frac

Unknown macro: {b^2}

)\ln(\frac

Unknown macro: {b}
Unknown macro: {a}

)]
$$
and
$$
\sigma_\theta = (\frac

Unknown macro: {tb^2N}

) [(1 - \frac

Unknown macro: {a^2}
Unknown macro: {b^2}

)(1+\ln(\frac

Unknown macro: {r}
Unknown macro: {a}

)) - (1 + \frac

Unknown macro: {r^2}

)\ln(\frac

Unknown macro: {b}
Unknown macro: {a}

)]
$$
where
$$
N = (1 - \frac

Unknown macro: {a^2}
Unknown macro: {b^2}

)^2 - 4(\frac

Unknown macro: {b^2}

)\ln^2(\frac

Unknown macro: {a}

)
$$

There is Winkler Bach Theory, where

Unknown macro: {latex}

$$
\sigma_x = \frac

Unknown macro: {M}
Unknown macro: {AR}

[ 1 + \frac

Unknown macro: {y}
Unknown macro: {Z(R + y)}

]
$$
where
$$
Z = -1 + \frac

Unknown macro: {R}
Unknown macro: {h} \ln[(R+\frac
Unknown macro: {2}

)/(R - \frac

Unknown macro: {h}

)]
$$

And there is the straight beam theory, where

Unknown macro: {latex}

$$
\sigma_x = \frac

Unknown macro: {My}
Unknown macro: {I}

$$

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
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 13.0 release, there may be compatibility issues when attempting to open with older 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.
