The Brittle Ring Test: A Simple and Reliable Method for Evaluating the Fracture Strength of Technical Ceramics—Theoretical and Experimental Investigations

open access: yesInternational Journal of Ceramic Engineering &Science, Volume 8, Issue 2, March 2026.
The study reviews existing formulas for the Brittle Ring test and introduces an adapted equation that most accurately determines the fracture strength of ceramic rings. Valid strength values can be obtained with minimal sample preparation when suitable geometric ratios are maintained, demonstrating the method's efficiency for technical ceramics ...

A dynamic tactile sensor on photoelastic effect

open access: yes, 2006
Certain photoelastic materials exhibit birefringent characteristics at a very low level of strain. This property of material may be suitable for dynamic or wave propagation studies, which can be exploited for designing tactile sensors.

RGB photoelasticity applied to the analysis of membrane residual stress in glass [PDF]

open access: yes, 2011
The measurement of residual stresses is of great relevance in the glass industry. The analysis of residual stress in glass is usually made by photoelastic methods because glass is a photoelastic material.

THE PHOTOELASTICITY OF RHOMBIC SYNGONY CRYSTALS

open access: yesЕлектроніка та інформаційні технології
The Rb2SO4 crystals were synthesized by slow evaporation of room-temperature aqueous solution of pure rubidium sulfate salts that had been recrystallized many times. The solution temperature was 310 K, controlled by a thermostat with an accuracy of 0.5 K.

Slit tube responses and rock fracture characteristics in slit charge blasting under high in situ stress

open access: yesDeep Underground Science and Engineering, Volume 5, Issue 1, Page 81-95, March 2026.
In this article, the finite element method‐smoothed particle hydrodynamics adaptive coupling algorithm is applied to numerically simulate and analyze the dynamic response of the slit tube and the crack propagation under high in situ stress. The dynamic response of the slit tube mainly exhibits radial response in the vertical direction of the slit and ...

An achromatic polarization retarder realized with slowly varying linear and circular birefringence

open access: yes, 2011
Using the phenomena of linear and circular birefringence we propose a device that can alter general elliptical polarization of a beam by a predetermined amount, thereby allowing conversion between linearly-polarized light and circularly polarized light ...
