Crack Growth Rate Analysis of Stress Corrosion Cracking [PDF]

open access: yesTehnicki vjesnik - Technical Gazette, 2021
A theoretical film rupture model was used for computational procedure to predict the crack growth rate within the Stress Corrosion Cracking (SCC) conditions. Chemical, electrochemical and mechanical aspects of the SCC were analyzed and set into the computer program to calculate crack growth rate.

Influence of microstructural discontinuities on the behaviour of long cracks in the VHCF regime for the aluminium alloys EN AW 6082 and EN AW 5083 [PDF]

open access: yesMATEC Web of Conferences, 2018
In the present study two different aluminium alloys, the precipitation hardening alloy EN AW 6082 (peak-aged and overaged) and the work-hardening alloy EN AW 5083 (soft annealed) were examined. Fatigue cracks were initiated by means of a focused ion beam

Fractal Analysis for Fatigue Crack Growth Rate Response of Engineering Structures with Complex Geometry

open access: yesFractal and Fractional, 2022
A growing fatigue crack in metallic materials and structures exhibits multifractal features that inherit signatures of the crack growth rate behavior of the material. This study exploits the recently established multifractal fatigue crack growth model to

Numerical simulation of grain-size effects on creep crack growth by means of grain elements [PDF]

open access: yes, 1998
The effect of grain size on creep crack growth is investigated by means of a numerical technique in which the actual crack growth process is simulated in a discrete manner by grain elements and grain boundary elements.
