Dear Onkar Kulkarni ,

To optimize the bending curvature by controlling the scribing parameters—the depth, number, and interval of the scribed grooves, finite element analysis was conducted on the bending tests of scribed polyethylene terephthalate films. Moreover, the influences of the parameters on the stress/strain near the grooves were investigated. The maximum stress/strain and curvature generally increased with an increase in depth, whereas these values decreased with an increase in number and intervals.

Hi Onkar Kulkarni . If you want to try Fiji (ImageJ), curvature can be measured semi-automatically with Kappa. But, of course, this requires an image of the beam. Check out the video tutorial here if you are interested: https://youtu.be/x0eGR7DwjfM?si=LI_-2d2RgH7XAe9W
