Fatigue crack characterisation in 2024-T351 aluminium alloy through SEM observation combined with the CJP model
نویسندگان
چکیده
This work characterises crack growth in AA2024-T315 by combining different methods to further increase the reliability of results. The Christopher-James-Patterson (CJP) model was fitted experimental data obtained digital image correlation (DIC). effective value CJP stress intensity factors were successfully correlated with ?K-da/dN curve as Scanning Electron Microscopy measurements depth striations on fracture surface. approach based fitting DIC and SEM observations allowed estimation opening closure loads propagation rate mode be effectively characterised.

Fatigue of Friction Stir Welded 2024-T351 Aluminium Alloy
Fatigue failure characteristics of friction stir welds in 13mm gauge 2024-T351 plate have been assessed. Failure occurred from either the weld region (nugget/flow arm) or from the material immediately surrounding the weld. Fatigue failure from the surrounding material was essentially conventional, initiating from large S-phase intermetallic particles and growing in a macroscopic mode I manner. ...
متن کاملCrack Behavior of the Aluminum Alloy 2024 Under Fretting Conditions
The initial stage of fretting fatigue crack growth is significantly influenced by tangential force induced by fretting action along the contact surface where a mixed-mode crack growth is involved. Fretting crack behavior of aluminum alloy 2024 was studied, taking into account the problem of contact asperities. Finite element was used for the determination of the stress field near the contact su...
متن کاملEffect of Tool Profile and Fatigue Loading on the Local Hardness Around Scratches in Clad and Unclad Aluminium Alloy 2024
Nanoindentation has been used to study the hardness changes produced by scratching of aluminium alloy AA2024, with and without a clad layer of pure aluminium. The hardness was mapped around scratches made with diamond tools of different profiles. One tool produced significant plastic damage with associated hardening at the scratch root, whilst the other produced a ‘cleaner’ cut with no hardenin...

متن کاملEnhanced Exponential Fatigue Crack Growth Model for Al-alloy
In the present investigation, an attempt has been made to use “exponential model” in the prediction of fatigue life without integrating the fatigue crack growth rate curve (FCGR). The obtained results are compared with experimental crack growth data obtained for 2024-T351 aluminum alloy for four bending V-Charpy specimens under constant amplitude loading in stress ratio range from 0.1 to 0.3 an...
