Study of short cracks under biaxial fatigue

open access: yesFracture and Structural Integrity, 2014
In this paper a methodology for evaluating crack initiation under biaxial conditions is presented. The methodology consists of evaluating the crack length automatically with digital processing of highmagnification images of the crack. The methodology was

Pressed lithium disilicate glass ceramics: Microstructural characterization, in vitro and in silico nonlinear dynamic analysis for biaxial flexural strength

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the mechanical properties of lithium disilicates, and to assess the predictive capability of in silico models for biaxial flexural strength (BFS). Materials and Methods Specimens of four heat‐pressed lithium disilicates (IPS e.max Press, Rosetta SP, LiSi Press, Vintage Prime Press) were obtained.

High magnification crack-tip field characterisation under biaxial conditions

open access: yesFracture and Structural Integrity, 2013
This work presents a novel methodology for characterising fatigue cracks under biaxial conditions. The methodology uses high magnification Digital Image Correlation (DIC) technique for measuring displacement and strain crack-tip fields. By applying micro-

Batteries From Reused, Recycled, and Surplus Materials

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 7, July 2026.
Batteries can become more circular by combining reuse, direct recycling, metallurgical recovery, and material sourcing from industrial surplus streams. This Review highlights how recycled and waste‐derived metals, carbons, polymers, electrolytes, and active materials can be reintegrated into current and emerging batteries, while emphasizing design ...

Biaxial flexural fatigue behavior of strain-hardening UHPFRC thin slab elements

open access: yes
The biaxial flexural fatigue behavior of thin slab elements made of strain-hardening Ultra High Performance Fiber Reinforced Cementitious Composite (UHPFRC) is investigated experimentally by means of the ring-on-ring test method.

Mixed‐Mode Stress Intensity Factor Evaluation via Thermoelastic Stress Analysis Including Non‐Adiabatic Correction

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 7, Page 2892-2907, July 2026.
ABSTRACT Characterization of the crack tip, such as the stress intensity factor (SIF), is a vital step for the assessment of fatigue crack growth and prediction of potential failure in engineering structures. This study investigates the use of thermoelastic stress analysis (TSA) for SIF evaluation, including a methodology for non‐adiabatic stress field

An effective method to investigate short crack growth behaviour by reverse bending testing

open access: yes, 2007
A reverse bending rig has the advantage of relatively cheap construction compared with servo-controlled machines, and its robustness and reliability make it ideally suited to long-term testing programmes.
