A damage mechanics approach to multiaxial fatigue [PDF]

, 2010
The fatigue assessment of structural components under a complex multiaxial stress history is one of the most difficult engineering challenge. As is well-known, several materials present a conventional fatigue strength at a given number of cycles under ...

Evaluation and visualization of multiaxial fatigue behavior under random non-proportional loading condition [PDF]

Fracture and Structural Integrity, 2017
In cyclic multiaxial stress/strain condition under nonproportional loading in which principal direction of stress/strain are changed in a cycle, it becomes difficult to analyze stress/strain ranges because of complexity of multiaxial stress/strain states

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

The Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

Multiaxial fatigue life predictions by using modified manson-coffin curves [PDF]

, 2004
In the present study, a novel multiaxial strain based approach is proposed and validated using a number of data sets taken from the literature. The plane experiencing the maximum shear strain amplitude (critical plane) is assumed here to be coincident ...

Probabilistic prediction of rate‐dependent rock strength using natural gradient boosting and Gaussian process regression

Deep Underground Science and Engineering, EarlyView.
Probabilistic natural gradient boosting and Gaussian process regression models accurately predict rate‐dependent rock strength across lithologies. Static strength and strain rate dominate, while geometric factors have minimal influence, enabling interpretable and uncertainty‐aware predictions for dynamic geomechanical applications. Abstract The dynamic

On the use of the Modified Wöhler Curve Method applied in terms of the Reference Radius Concept to perform the multiaxial fatigue assessment of welded joints [PDF]

, 2010
The present paper summarises an attempt of using the Modified Wöhler Curve Method (MWCM) in conjunction with the reference radius concept (rref=1 mm) to estimate lifetime of welded joints subjected to multiaxial fatigue loading.

Comorbid Depression in Hospitalised Youth With Anorexia Nervosa: Characteristics, Correlates, and Impact on Weight Gain and Treatment Duration

European Eating Disorders Review, EarlyView.
ABSTRACT Objective Anorexia nervosa (AN) is associated with high rates of comorbidities. The impact of comorbid depression‐spectrum disorders (DSDs) in AN patients on the outcomes of inpatient treatment is insufficiently studied. Method Retrospective study of youth with AN (9–18 years), admission weight < 10th body mass index (BMI) percentile ...

Multiaxial endurance limit estimation in notched structural components using a combined critical point-critical plane approach [PDF]

, 2007
A high-cycle multiaxial fatigue criterion, based on a combined critical point-critical plane approach, is used to estimate the multiaxial endurance limit in notched metal structural components.

Axial-torsional fatigue of pultruded glass-fiber tubes

Results in Engineering
Fatigue characteristics of the pultruded glass-fiber composites were extensively investigated experimentally. Tubular specimens with three-layer structure (mat, roving, mat) were subjected to simultaneous cyclic axial and torsional loads to initiate ...

A bandwidth correction to the Allegri-Zhang solution for accelerated random vibration testing

MATEC Web of Conferences, 2018
In 2008, Allegri and Zhang published a study [Int. J. Fatigue. 2008, 30(6):967-977] in which they provided an exact analytical solution to the inverse scaling law for accelerated vibration tests of linear systems submitted to stationary Gaussian ...
