On short cracks that depart from elastoplastic notch tips [PDF]

open access: yesFracture and Structural Integrity, 2017
The behavior of short cracks that depart from elastoplastic notch tips is modeled to estimate the stresses required to initiate and to propagate cracks in notched structural components, and to evaluate the size of tolerable crack-like defects under ...

Study of short cracks under biaxial fatigue [PDF]

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

Stress intensity factors of partially compressed centrally cracked disk with frictional crack surfaces

open access: yesMaterials Research Express, 2023
This work analytically calculates mixed-mode I/II stress intensity factors for an inclined central frictional crack in a Brazilian disc partially compressed with a uniform pressure. Wide-range controlling parameters are invoked.

Study of Short Cracks Growth Behavior for Duralumin 7075- T6 Enhanced by Artificial Ageing as Thermal and Chemical Treatments Under Rotating Bending Loading [PDF]

open access: yesEngineering and Technology Journal, 2013
The fatigue life of ductile metals is controlled mainly by the propagation life of a short surface crack; to clarify the growth behavior of short cracks is crucial factor to the safe design of smooth surface members.

The deformability of the stress-strained concrete strips between the cracks during the short-term dynamic loading [PDF]

open access: yesMATEC Web of Conferences, 2020
The formation of non-intersecting cracks in stress-strained ferroconcrete elements leads to separation of concrete strips between the cracks. The results of the experimental research indicate a significant decrease of the durability and deformability of ...

Initiation and growth behavior of very-long microstructurally short fatigue cracks [PDF]

open access: yesFracture and Structural Integrity, 2013
The present paper describes a novel experimental technique recently presented that allows one to study interactions between the crack and microstructural barriers with an unprecedented level of ease and detail. The method consists in increasing the grain

Crack Growth Model for Estimating the Fatigue Life under Variable loading [PDF]

open access: yesEngineering and Technology Journal, 2011
This paper examines the fatigue short and long cracks behaviour in 2024 T4 aluminum alloy under rotating bending loading and stress ratio R = -1. In the short cracks region, cracks grow initially at a fast rate but deceleration occurs quickly and ...

Detection and Characterization of Short Fatigue Cracks by Conduction Thermography

open access: yesEngineering Proceedings, 2023
Stimulated thermography is a very common non-destructive testing (NDT) technique used for a wide range of applications and materials. An external excitation source is required to stimulate the component and detect defects.

Short Fatigue Crack Growth in a Residual Stress Field in a 7075 Al-Alloy after Shot Peening

open access: yesCommunications, 2012
The paper contains results of an investigation of effects of shot peening on growth of physically short fatigue cracks in a 2.4 mm thick sheet of an aircraft V-95 Al-alloy (a type of a 7075 alloy), clad with a 7072 Al-alloy (Al-Zn1).
