Model physically associating gels deformed in shear over a wide range of reduced rates displayed evidence of strain localization. The nonlinear stress responses and inhomogeneous velocity profiles observed during shear rheometry coupled with particle tracking velocimetry were associated with the occurrence of rate-dependent banding and fracture-like responses in the gel. Scaling law analysis fr...

Compression-compression fatigue testing of metallic-glass foam is performed. A stress-life curve is constructed, which reveals an endurance limit at a fatigue ratio of about 0.1. The origin of fatigue resistance of this foam is identified to be the tendency of intracellular struts to undergo elastic and reversible buckling, while the fatigue process is understood to advance by anelastic strut b...

A crack moving dynamically through a sheet of Polymethylmethacrylate at high average velocity is found in reality to propagate in a non-steady, periodic, and perhaps discontinuous fashion. The spatial period of the fracture process in the direction of travel, or banding morphology, is of millimeter size and is consistent both in magnitude and discontinuous nature with a crazing mechanism propos...

Bendability is an important property of ultrahigh-strength steels since the typical applications such materials include structures manufactured by air-bending. Conventional methods to evaluate bendability, as bending test according standard VDA-238 or conventional tensile do not provide sufficient information bendability due average nature material response in these tests. In this study, mechan...

-Recent studies of the initiation and propagation of shear bands using doubly or singly notched plates loaded asymmetrically have yielded valuable insight into this phenomenon. The same experiments also demonstrated that the shear banding mode of failure and a more brittle, "fracture", mode of failure can coexist in the impact-loaded specimens and transitions between the two modes were document...

The chromosomal banding properties of Oxynoemacheilus simavicus (Balık & Bănărescu, 1978) were revealed out by C-banding and silver staining. Constitutive heterochromatin regions determined on the pericentromeres most chromosomes C-banding. Otherwise, nucleolus organizer (NORs) observed short (p) arms one middle-sized submetacentric (sm) chromosome pair Also, Ag-NOR size number polymorphism...
