چکیده
Fatigue crack growth in Al 2024 and 7050 specimens was assessed experimentally numerically. In the experimental investigation, various specimen configurations loading conditions were used to achieve pure mode I, II, mixed I/II, I/III, I/II/III. Sample as follows: first, compact tension shear (CTS) reproduce mode-I initial mode-II conditions; second, surface (SCT) analyze behavior of semielliptical cracks mixed-mode third, hollow cylindrical (HC) with fatigue under complex stress state. numerical study, finite element method (FEM) simulations performed by means FRANC3D ABAQUS solver. The predictions validated results. These resulted be accurate estimation across broad range investigated conditions.

An atomistic investigation into the nature of near threshold fatigue crack growth in aluminum alloys
Despite decades of study, the atomic-scale mechanisms of fatigue crack growth remain elusive. Here we use the coupled atomistic–discrete dislocation method, a multiscale simulation method, to examine the influence of dislocation glide resistance on near-threshold fatigue crack growth in an aluminum alloy. The simulations indicate that the threshold increases with an increase in dislocation glid...
متن کاملInvestigating the Effects of Cold Bulge Forming Speed on Thickness Variation and Mechanical Properties of Aluminum Alloys: Experimental and Numerical
In this work, cold bulge forming of an Aluminium-Magnesium (Al-Mg) sheet with a solid bulging medium is performed experimentally and numerically. Mechanical properties and thickness variations of Al-Mg sheet are evaluated before and after the forming process. The results indicated that the Al-Mg sheet has taken the desired shape without necking using the cold bulge forming process. Also, the...
متن کاملNumerical Investigation on Stable Crack Growth in Plane Stress
Large deformation finite element analysis has been carried out to investigate the stress-strain fields ahead of a growing crack for compact tension (a/W=0.5) and three-point bend (a/W=0.1 and 0.5) specimens under plane stress condition. The crack growth is controlled by the experimental J-integral resistance curves measured by Sun et al. The results indicate that the distributions of opening st...
