Analysis of Stress and Fracture Strength of Zirconia Implants after Cyclic Loading [PDF]
Materials Research, 2015 The aim of this study was to manufacture a new zirconia implant (Y-TZP) and to evaluate the fracture strength and stresses generated after cyclic loading compared to titanium implants. Thirty-three zirconia and titanium implants were fabricated.

The Refraction Indices and Brewster Law in Stressed Isotropic Materials and Cubic Crystals
Crystals, 2021 We study the elasto-optic behavior of stressed cubic crystals (all classes) and isotropic materials (like e.g., glasses). We obtain the explicit dependence of the refraction indices on the stress (either applied or residual), as well as a mild ...

Evaluation of stress intensity factor of multiple inclined cracks under biaxial loading
Fracture and Structural Integrity, 2012 A finite rectangular plate of unit thickness with two inclined cracks (parallel and non parallel) under biaxial mixed mode condition are modelled using finite element method. The finite element method is used for determination of stress intensity factors

Photoelastic residual stress measurement in nonaxisymmetric glass containers
EPJ Web of Conferences, 2010 Residual stresses in axisymmetric glass containers are mostly measured with integrated photoelasticity. However, many containers, e.g. cosmetic bottles and bottles of expensive alcoholic drinks, often have a non-axisymmetric form.

High Load-Induced Birefringence of PMMA Investigated in VIS/NIR Spectral Range
Advances in Electrical and Electronic Engineering, 2019 In the paper, we present the results of an investigation of polymethylmetacrylate’s birefringence induced due to applying high-load. The stress-induced birefringence of the polymethylmetacrylate samples was experimentally investigated by an apparatus ...
