## Overview
This project investigates the application of DIC on images of a brass specimen undergoing a tensile test. These were provided by [John Laidlaw](https://me.engin.umich.edu/people/staff), Professional Engineer at the University of Michigan Mechanical Engineering Department.
The goal was to analyze displacement and strain fields in the images to create a stress-strain curve to determine material properties like Young's modulus, Poisson's ratio, ultimate tensile strength, yield strength, and fracture strength. A summary of our findings can be found in our [report](EECS_442_Computer_Vision_DIC_Project.pdf) for [EECS 442: Computer Vision](https://web.eecs.umich.edu/~fouhey/teaching/EECS442_W19/) course at the University of Michigan. You can view the latest report on [Overleaf](https://www.overleaf.com/read/whvdsndzrvqw).
Our source code for analyzing the images can be found in the **src** folder. The plots generated for the report can be found in the **Plots** folder. The images of the brass specimen can be found in the **Images**.
## Motivation
The motivation for this project came from Sravan's [MECHENG 395: Laboratory I](https://me.engin.umich.edu/academics/courses) course at the University of Michigan in which a tensile test of brass was conducted and analyzed using [LaVision](https://www.lavision.de/en/) DaVis software. After a conversation with [Dr. Michael Thouless](https://me.engin.umich.edu/people/faculty/michael-thouless), who had worked on a paper using DIC to investigate the cohesive zone in a double-cantilever beam, we determined that this would be a cool project to combine our interest in Mechanical Engineering and Computer Science.
