Finalizing Research

WEEK 9

This week we've been gathering all of our data to prepare a poster to present at both Oakland University and Michigan State University. Pretty satisfied with the results, though more time would've been necessary to advance the research further. Below is a copy of our poster, ready to present.

Qualitative Success

WEEK 8-9

The reciprocating motion is behaving as expected now.  We had a slight complication because it turned out the experiments are being run at 8Hz, so after some adjustment we got the model to run.  The GIF below shows the motion we've been looking for. Also shown are isothermal contour and temperature distribution GIFs, shown in the order listed.

We've also had success with the flash model. Below shows the temperature distribution comparison of constant versus variable thermal properties. The comparison is shown at different depths in the solid to illustrate the temperature gradient through the thickness of the specimen. Also shown is the maximum surface temperature versus time.

Mesh and Time Step Refinements

WEEK 6-7

Reciprocating models are getting much more refined. Finer meshing and time steps allow for more accurate models. The GIFs below can be compared to those posted earlier to show the development.

Flash Model simulations going well, just need to develop ways to analyze the data more thoughtfully, results to be posted soon.

Flash Model Progress

WEEK 5

Got the flash models to run finally. Still struggling with the reciprocating motion for the bulk model. Results to follow for the flash model

Flash models taking far too long to run on the lab computers, had to switch to the laptop and run the simulations through the Linux server 'virtual pc'.

Reciprocating Motion

WEEK 3-4

Reciprocating motion simulation proved more difficult than originally anticipated.  Here are some videos of the early stages of the reciprocating motion.

3D Images from Previous Simulations

WEEK 1-2

Here is a collage of some models retrieved from of the transient wear simulation performed by the group preceding us.

You can see the red spot on each image, where the ball is in contact with the disk, and the heat dissipation around the path of the ball.
