Solid Works Brain Probe Model

But the thing is: I modelled the probe as a hole, instead of as another solid. To be added with Assembly.

Pin Push In animation :)

I basically inversed the displacement value. Some limitations, the pin is already inside the block, so no penetration effect. FYI, the pin is bigger than the block hole.

Pin Pull Out Animation

From Ansys Tutorial. Similar to the project, but need to tweek:

- push in, instead of pull out.

- viscoelastic instead of elastic for the brain

- hydrogel coating

Development thus far

- Using Solid Works to develop the model, a cylinder with a hole of the shape of the brain probe
- Investigating into Ansys, Tutorial Chapter 8: Contact Tutorial: Inteference Fit and Pin Pull Out Contact Analysis.
- Planning to make the models in Solid Works then importing them to ANSYS.
- Investigating into visco-elastic properties of brain tissue. How to input the data into the material properties.
- Expected outcome of the project: an animation of stress and strain distribution of the brain tissue, as the brain probe is penetrating and as the hydrogels expanding.
- Hypothesis: the stress and strain are not significant, thus the inflamation observed during implant is caused by biological phenomenon.
- Hoping to get training / course in Ansys / Solid Works.
- Investigating into "animation" of Solid Works.

First Entry

First of all, I would like to thank my friend for the idea.

The purpose of this blog is to update the development of the Final Year Project: The Effect of Probing the Brain with a Neural Probe: an Analysis of the stress and strain distribution in the Brain Using Finite Element Method.

Any comments are welcome. :)
