Abstract The present work aims for an initial computational simulation with finite element analysis of the friction riveting process. Knowledge and experimental data from AA2024-T351 polyetherimide supported simulation. Friction is a friction-based joining technology capable connecting multiple dissimilar overlapping materials in fast simple manner. In this paper, plastic deformation metallic r...

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 striat...

Abstract This paper investigates the influence of stress state on equivalent plastic fracture strain in 2024-T351 aluminum alloy. Eighteen unique states at failure—with triaxialities ranging from 0.388 (compressive) to −0.891 (tensile) and Lode parameters −0.978 1.000—are explored through mechanical experiments specimens with various geometries under multiple loading conditions. These include t...

In the present study, treatment of HEK-293 cells with the synthetic small molecule N-iodoacetyl-tryptophan (I-Trp) at submicromolar concentrations efficiently induced cell apoptosis as judged from the accumulation of sub-G(0) cells and intracellular DNA fragmentation. Activation of all intracellular caspases, except caspase-1, was detected in I-Trp-treated cells. Proteomic analysis revealed tha...
