Abstract (es)
Análisis de campos de esfuerzos en imágenes de fotoelasticidad son llevados a cabo mediante descriptores de textura en este artículo. En este caso, los descriptores considerados permiten identificar zonas con altas concentraciones de esfuerzo, incluso en casos con pérdida de contraste, los cuales son por lo general atribuidos a la baja resolución espacial de las franjas. De manera adicional, en este trabajo se analiza la variación en la densidad de franjas en términos de la longitud de onda. Esto último se hace extendiendo la generación de imágenes de fotoelasticidad en el infrarrojo lejano.
Abstract (en)
In this paper, stress fields analysis in photoelasticity digital images is carried out by using texture descriptors. In this case, such descriptors can identify zones with high stress concentration, even for cases with low spatial resolution in fringe patterns. In addition, this paper analyzes the variation that those fringes experience in function to wavelength. For this process, generating the photoelasticity images is extended to the far infrared.
