The transition between necking-mediated tensile failure of glasses, at elevated temperatures and/or low strain-rates, and shear-banding-mediated failure, high is investigated using experiments on metallic glasses atomistic simulations. We experimentally simulationally show that this occurs through a sequence macroscopic patterns, parametrized by the ultimate strength. Quantitatively analyzing s...

Pendant droplets of water and paramagnetic solutions are studied in the presence uniform nonuniform magnetic fields produced by small permanent magnet arrays, both static conditions during dynamic pinch-off. Static measurements droplet shape analysed terms an apparent surface tension {\gamma}app or effective density \r{ho}eff. The change deionized a field 450 mT is insignificant, 0.19 - 0.21 mN...

Motivated by a model that qualitatively captured the response of vertically aligned carbon nanotube (VACNT) pillars in uniaxial compression, we consider the uniaxial tensile response of a class of compressible elastic-viscoplastic solids. In Hutchens et al. [“Analysis of Uniaxial Compression of Vertically Aligned Carbon Nanotubes,” J. Mech. Phys. Solids, 59, pp. 2227–2237 (2011), Erratum 60, 17...

[1] Comparison of analogue experiments at crustal and lithospheric scale provides essential information concerning the mode of deformation during lithospheric extension. This study shows that during extension, lithospheric deformation is controlled by the development of shear zones in the ductile parts. At lithospheric scale, the global deformation is initiated by the rupture of the brittle man...

The exact stress–strain curve can be directly identified from uniaxial tension experiments up to the point of onset diffuse necking. To gain insight into post-necking hardening response metals, other experimental methods such as bulge, compression or torsion are typically employed. Here, we introduce idea using surround DIC obtain accurate specimen shape measurements tensile specimens with rect...

We investigate the dynamics of the capillary thinning and break-up process for low viscosity elastic fluids such as dilute polymer solutions. Standard measurements of the evolution of the midpoint diameter of the necking fluid filament are augmented by high speed digital video images of the break up dynamics. We show that the successful operation of a capillary thinning device is governed by th...
