Poisson’s ratio, ν, is a fundamental mechanical parameter that describes the ratio of the lateral to the longitudinal strain of a material under mechanical load. The precise value of the Poisson’s ...

In this study, we show that negative Poisson’s ratio is a feature of several metal plates with the nanometer thickness under finite strain, contrasting to their bulk counterparts that exhibit positive ...

The year is 1981. The scene, the R&D department of a major aircraft company. “Uh, sir?” the young engineer stammers. “Sir? I am concerned about these stiffeners you want to bond onto the skins.” “What ...

Metal powders are used to produce a variety of industrial parts and products. A number of techniques are used to manufacture parts from metal powders, with two popular techniques being sintering and ...

This article looks at how Dynamic Image Analysis (DIA) and Laser Diffraction (LD) technologies may be used to characterize the size and shape of common metal powders and metal alloys, utilizing the ...
