TLDR
In this article, the effect of fractal concentrators is evaluated by means of digital photoelasticity by considering a circular disc of epoxy resin, a Canon color camera and a Baumer VCXU-50MP polarized camera.Abstract:
Identifying the state of stress around a concentrator is essential in a loaded structure. However, most studies are based on circular geometries, leaving aside complex ones such as fractals. In this paper, the effect of fractal concentrators are evaluated by means of digital photoelasticity by considering a circular disc of epoxy resin, a Canon color camera and a Baumer VCXU-50MP polarized camera. Additionally, a phase map was obtained with phase shifting, and phase wavelengths stepping algorithms. The digital photoelasticity executed detection of stress fields related to the fractal concentrator.read more

Digital photoelasticity and DIC applied to stress and strain hybrid evaluation of bioinspired structures from rice root cross-section
Juan Camilo Hernández Gómez,Juan Carlos Briñez de León,Salomon Perez-Atencia,Alejandro Restrepo-Martínez +3 more
TL;DR: In this paper, the authors analyzed differences in the mechanical response of a stress concentrator when comparing conventional rings and their respective bio-inspired representation and found that the bioinspired geometries are more sensitive to stress and strain than conventional rings.
