Photoelastic analysis of thermal stresses
Developments in the application of photoelastic techniques to the study of thermal stress problems are here briefly reviewed, then followed by a short introduction to the relevant photoelastic and thermoelastic theories. A new method for the study of transient thermal stresses; as well as stresses …

A photoelastic study of stress distribution in a spur gear tooth
… make it difficult to get a general solution. The photoelastic method is an effective one for making a static study of gear stress, but it is understood that this method can not solve the whole problem, Since if the static stresses are considered further studies covering the notch sensitivity, …

Finite element simulation of Durelli's photoelastic stress minimization method for shape optimization
… Element Method (FEM) was used to simulate the Photoelastic Stress Minimization (PSM) method developed by Durelli to solve the problem of finding the optimal stress raiser profiles in isotropic and advanced composite structures. In Durelli's method, material in lowly stressed regions of the …

Photoelastic study of dense granular free-surface flow rheology and size segregation
… Here we describe a novel adaptation of the photoelastic technique and explain how we applied it in an original setup to offer unprecedented insight into the force distribution within granular flows, as this has never been achieved experimentally in dynamic systems before. Firstly, using …
