On this page you will find various resources related to geodynamics research. This is a work in progress.

## Research Summaries

These are some notes on calculations and related calculation and plotting scripts. (Yes, I see that there’s just one, not some… its a work in progress…).

- Approximation to Peierls Creep Flow-law that allows the flow law to be rewritten in terms of stress as a function of strain-rate. This derivation follows the approach given in Kameyama et. al.,
*Thermal-mechanical effects of low- temperature plasticity (the Peierls mechanism) on the deformation of a visco-elastic shear zone*, Earth and Planet. Sci. Lett.,**168,**159–172, 1999.- A python script that plots the approximation derived above and the exact solution so that one can test the fitting factor for the stress range of interest in the model, and a PDF plot of the approximation for one value of the fitting factor.
- A python script comparing published Peierl’s Creep flow laws and a PDF of the plot that is generated.

## Jupyter Noteboooks

Jupyter notebooks for a variety of geodynamics related calculations. Many of these are for analytic solutions for flow or forces related to plate, slab or mantle flow. The notebooks are a great way to combine the background information, the python script for doing the calculation and figures. However, I have also included a PDF of the notebook in case you are not yet a jupyter notebook user.

**Warning:** I have made every effort to insure there are no errors in these scripts, but it is not smart to assume that they are in fact error free. If you use them, you should check the results against the cited publications and common sense.
