From the classical studies of interacting fields such as in thermoelasticity, photoelasticity, etc., nowadays much attention is paid to real-life systems whether in biology or man-made systems (multi-agent systems, econophysics, just to name a few examples) where nonlinearity, heterogeneity, hierarchies, and non-stationarity describe the governing properties or mechanisms.
In the last decades, many measurement approaches were used to detect the SIF near the crack in transparent materials including photoelasticity [12, 13], coherent gradient sensing (CGS) [14-16], and digital coherent sensing (DGS) [17-19].
Stress concentration factors have been calculated for different geometries and ratios, the most complete review of stress concentrators with various geometries using the photoelasticity method is presented in [4].
Si bien la literatura reporta multiples metodos en fotoelasticidad para extraer informacion de los esfuerzos a partir del procesamiento de los patrones de franjas, tales como corrimiento de fase (phase shifting) [5], demodulacion de color (three fringe photoelasticity) [6], tecnicas de problema inverso (inverse problem) [7], la relacion entre los esfuerzos y sus direcciones forman zonas donde la informacion recuperada es incorrecta (inconsistencias y ambiguedades), como fue explicado por Ramesh en [2].
(10),52) For instance, two-dimensional laboratory model experiments utilizing dynamic photoelasticity in conjunction with high-speed cinematography, together with finite difference numerical calculations, have illustrated that a slip pulse can run at the Rayleigh wave speed of the acoustically stiffer material and dynamic rupture-induced wave patterns are controlled by the acoustic mismatch of the two materials sandwiching the interface (Fig.
