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.
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].
(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.

photoelasticity was employed to evaluate the simulated flow-induced stress indirectly in this study.
A new operation for arthroplasty of the hip based on biomechanics,
photoelasticity, fast-setting dental acrylic, and other considerations.
The
photoelasticity phenomenon was first demonstrated by Scottish physicist David Brewster in the early 19th century.
Photoelasticity is an experimental technique for stress and strain analysis that is particularly useful for the samples with a complex geometry and loading conditions.
