These codes go with the analysis for the data I am processing for Dynamic Buckling Analysis of rubber.

1/2. Buckling Analysis via Electronic data and Images for Threads/rods/membranes

In this project, I'm measuring certain electronic data amplified with INA110KP Integrated Circuit chip via NI-SCB-68 and PXI-1033 at intervals of 20μs.The entire process is recorded with a Fast camera (Phantom Miro M310) at intervals of∼66μs. The images are analysed with MATLAB Image Processing Toolbox. These codes can be used to measure lengths with sub-pixel resolution. I am using these for Dynamic Buckling Analysis of experiments performed in Soft Matter Lab at TIFR.

Input

We take an image that looks as below:

Output

And we get detected points in blue and red as I've labeled on the above black and white image:

2/2. Numerical Solution for Euler Bernoulli fourth order differential equation

We present a solution using Method of Lines.
