Formability of friction stir welding AZ31 magnesium alloy sheets

open access: yes, 2010
The formability of friction stir welded AZ31 magnesium alloy sheets was investigated by means of umaxial tensile and hemispherical punch tests performed under different process conditions The results of the tensile tests were analysed in terms of flow ...

Experimental investigations on forming limit diagram of ultra thin SS 304 steel : effect of circular grid size, sheet orientation, punch size and deformation speed [PDF]

open access: yes, 2019
In the present work, SS 304 sheet of 200 μm thickness was used to experimentally evaluate the forming limit diagram (FLD). In this context, a sub-size limiting dome height (LDH) test setup was developed to deform rectangular specimens of different widths

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

open access: yesThe Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

The Implementation of the Vegter yield Criterion and a physically based hardening rule in Finite Elements [PDF]

open access: yes, 1998
A new material description for sheet metal forming using Finite Elements has been developed. The description consists of a yield criterion and a hardening rule.

Re‐evaluation of a soft crested Edmontosaurin, with implications for hadrosaurid life appearance and diversity

open access: yesThe Anatomical Record, EarlyView.
Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and

Different shape but the same topographical complexity—The lingual gross anatomy of the Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

open access: yesThe Anatomical Record, EarlyView.
Abstract Despite the distinctly different shapes of their tongues, the tongue gross anatomy of Saimaa ringed seal closely resembled that of Baltic ringed seal. There were no differences in the extrinsic and intrinsic tongue muscles or their associated vascularization and innervation between Saimaa and Baltic ringed seals.

Room Temperature Formability of Mg Alloys

open access: yes, 2019
Room temperature formability of twin-roll cast Mg alloys has been investigated and correlated with their work hardening behavior. Tensile properties of these alloys were measured and their work hardening behaviour was analysed by using constitutive ...

Effects of Wheat Bran‐Derived Arabinoxylan Oligosaccharides on Dough and Noodle‐Making Properties

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives This study investigates the structural modifications of arabinoxylan (AX) through enzymatic hydrolysis and evaluates the potential application of arabinoxylan oligosaccharides (AXOS) as functional ingredients in wheat noodles, contrasting their effects with those of native AX.

An accessible microfluidic perfusion platform for time‐restricted control of zebrafish embryonic patterning

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Understanding the dynamic nature of developmental networks requires live imaging techniques capable of capturing real‐time developmental processes in wild‐type and mutant embryos as they are exposed to pharmacological perturbations. A peculiar developmental patterning process in early vertebrate embryos is the sequential segmentation of ...

Transient Stress Relaxation Test to Identify Material Constants in Dislocation Density Model

open access: yes, 2022
The constitutive behavior of metallic materials in terms of dislocation kinetics can be successfully described using a dislocation density-based model. Although the kinetics of thermally activated plastic deformation is well described by such models, the
