Stress intensity factor threshold in dental porcelains
Journal of Materials Science: Materials in Medicine, 2007 The stress intensity factor threshold (KI0) is related to the stress level at which cracks start to grow stably, causing the weakening of porcelain prostheses during their use. The values of KI0 of seven dental porcelains (with and without reinforcing leucite crystal, KAlSi2O6) stored in air (22 degrees C, 60% relative humidity) and artificial saliva ...

Stress Intensity Factor calculation from displacement fields
Frattura ed Integrità Strutturale, 2017 In the last two decades, visual image techniques such as Digital Image Correlation (DIC) enabled to experimentally determine the crack tip displacement and strain fields at small scales. The displacements are tracked during loading, and parameters as the Stress Intensity Factor (SIF), opening and closing loads, T-stress can be readily measured.

Mode i stress intensity factors of slanted cracks [PDF]
, 2017 The solutions of stress intensity factors of slanted cracks in plain strain plate are hard to find in open literature. There are some previous solutions of stress intensity factors available, however they are not studied completed except for the case of ...

Stress Intensity Factors - T-Stresses - Weight Functions
, 2008 Failure of cracked components is governed by the stresses in the vicinity of the crack tip. The singular stress contribution is characterised by the stress intensity factor K, the first regular stress term is represented by the so-called T-stress. Sufficient information about the stress state is available, if these two parameters are known Results for ...

Cracking Characteristics of Different Crack Forms in Pavement under Moving Load
Engineering TransactionsIn road engineering, the crack damage problems are one of the essential research areas that need to be emphasized. However, there have been few researches on the effects caused by different crack forms, e.g., the impacts of the distribution and ...

Fracture mechanics approach to design analysis of notches, steps and internal cut-outs in planar components [PDF]
, 2007 A new approach to the assessment and optimization of geometric stress-concentrating features is proposed on the basis of the correspondence between sharp crack or corner stressfield intensity factors and conventional elastic stress concentration factors (

The centrally cracked Brazilian disc: implications and solutions in case of closing cracks
Journal of the Mechanical Behavior of Materials, 2014 A recently presented closed-form analytic solution for the displacement field and stress field in a cracked Brazilian disc, under uniform radial pressure along two symmetric arcs of its periphery, revealed that for a wide range of crack-axis inclinations,
