Revisit on the analytic formulations of principal stress orientation in fracture mechanics
TL;DR: In this paper, the principal stress values and orientations were determined using Eigenvalue and Eigenvector approach and the principal stresses were studied, and it was found that principal stress orientations are insensitive towards the change in stress field parameter in the case of single parameter equation.

3D investigation of photonics elements by means of interferometric and photoelastic tomography
TL;DR: In this paper, the authors presented interferometric and photoelastic tomography methods applied for the 3D studies of refractive index (n) and birefringence (B) in photonics components such as optical fibres and microelements produced or replicated by a variety of novel technologies including deep proton writing (DPW) and hot embossing technology.

Analysis of a complex shape chain plate using Transmission Photoelasticity
N. Dasari,K. Ramesh +1 more
TL;DR: In this article, the authors used the transmission photoelastic technique to estimate the stress distribution and its concentration zones in a complex chain plate when it is loaded and showed that the chain fatigue life was observed only 20 to 25% of the total life of a chain, assembled without an offset plate.

Experimental Analysis of Mechanical Behaviour of Advanced Materials
TL;DR: Instead of a narrow understanding of a mechanical property as a constant magnitude obtained from the handbook or a database, modern researchers dealing with real-life applications of advanced materials should rather consider it as a multi-parametric function and, in some cases, even a statistic one.

Full-Field Isoclinic Evaluation in Digital Phase-Shifting Photoelasticity Applied to C-Shaped Model*
TL;DR: In this paper, the isoclinic parameter in digital photoelasticity is evaluated based on the four-step color phase shifting technique and the phase unwrapping (PU) algorithm.
