Abstract

The program FleX (Flexural deformation for Xtals) has been developed for a quick, easy and accurate evaluation of the maximum deformation reached in flexible crystals from a simple optical microscope picture. The program takes advantage of computer vision libraries to find a bent crystals contours and fit the contours to semicircles. It can, then, calculate its theoretical maximum deformation along its long axis using equations from the Euler-Bernoulli beam theory.
