The images of the brass specimen can be found in the **Images**. +## Images and Data +Images of brass specimen undergoing a tensile test were provided by John Laidlaw. The TIFF images were captured with a 5 megapixel [Point Grey](https://www.flir.com/iis/machine-vision/) camera and lens. A LabView program was developed to synchronize the data and image capture throughout the tensile test. John and Dr. Thouless investigated two alternative, open-source software to perform the analysis: +* [ncorr](http://www.ncorr.com/) (MATLAB) +* [GOM Correlate](https://www.gom.com/3d-software/gom-correlate.html) (2D is free) + +The data file contains a column with the frame number to sync the data and images. All the images are numbered in sequence (i.e. frame number) + ## 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. \ No newline at end of file
