Wall panel's analysis using photoelastticity

Photoelasticity is an experimental technique for stress and strain analysis that is particularly useful for members having complicated geometry, complicated loading conditions, or both. For such cases, analytical methods (that is, strictly mathematical methods) may be cumbersome or impossible, and analysis by an experimental approach maybe more appropriate. While the virtues of experimental solution of static, elastic, two dimensional problems are now largely overshadowed by analytical methods, problems involving three dimensional geometry, multiple component assemblies, dynamic loading and inelastic material behavior are usually more amenable to experimental analysis. References, figures and tables must not be given in Summary. The name photoelasticity reflects the nature of this experimental method: photo implies the use of light rays and optical techniques, while elasticity depicts the study of stresses and deformations in elastic bodies. Through the photoelastic-coating technique, its domain has extended to inelastic bodies.
