In traditional sheet metal forming processes, a thin is deformed at relatively low speeds. However, more and the speed of production processes increased, very often to take advantage beneficial implications that high strain rates can have on formability certain metals. this work, effect rate anisotropic behavior Ti6Al4V investigated performing tensile tests in different orientations, namely 0 o...

Biochar is considered to be a promising material for heavy metal immobilization in soil. However, the immobilization mechanisms of Zn(2+) on biochars derived from many common waste biomasses are not completely understood. Herein, biochars (denoted as PN350, PN550, WS350, and WS550) derived from pine needle (PN) and wheat straw (WS) were prepared at two pyrolysis temperatures (350 °C and 550 °C)...

Asymmetric sheet rolling is a process used when there are differences in any technological parameters the horizontal plane across width of deformation zone or vertical between top and bottom surfaces zone. Asymmetry can either have random causes, it be created purposefully to reduce force, improve flatness, minimize ski effect, obtain thinner sheets for grain refinement improvement texture mech...

When the dimensions of a metallic conductor are reduced so that they become comparable to the de Broglie wavelengths of the conduction electrons, the absence of scattering results in ballistic electron transport and the conductance becomes quantized. In ferromagnetic metals, the spin angular momentum of the electrons results in spin-dependent conductance quantization and various unusual magneto...

A strain energy function for finite deformations is developed that has the capability to describe the nonlinear, anisotropic, and asymmetric mechanical response that is typical of articular cartilage. In particular, the bimodular feature is employed by including strain energy terms that are only mechanically active when the corresponding fiber directions are in tension. Furthermore, the strain ...

A recently developed crystal-mechanics-based constitutive model for polycrystalline shape-memory alloys (Thamburaja and Anand [1]) is shown to quantitatively predict the in-plane anisotropy of superelastic sheet Ti-Ni to reasonable accord.
