Response of granular powders to uniaxial loading and unloading

Powder Technology, 2001
Abstract This study examines the effects of organic binder content and binder plasticity on the stress–strain response of a poly(vinyl alcohol) (PVA)-containing spray dried alumina powder (A16SG) in uniaxial compaction and ejection. Binder content ranged from 2.45 to 7.80 wt.% and the binder glass transition temperatures (Tg) ranged from −32°C to +35°

Viscous Sintering under a Uniaxial Load

Journal of the American Ceramic Society, 1986
An analysis is presented for viscous sintering under a uniaxial load; numerical results are presented for compressive loads. The load increases the axial contraction rate, hut counteracts the radial contraction rate. When the load is similar in magnitude to the capillary stress driving sintering, the radius remains essentially ...

Optimization of Reinforced Concrete Columns Subjected to Uniaxial Loading

2015
The distance from extreme compression fiber to neutral axis (c) is depended to combinations of axial load and flexural moment capacities of reinforced concrete (RC) columns. Since c is depended to different internal forces, the value of c cannot be found without assuming the final design.

Confined Concrete Subjected to Uniaxial Monotonic Loading

Journal of Engineering Mechanics, 1998
The behavior of concrete confined with carbon and glass fiber wraps is determined by uniaxial compression tests of filament wound composite cylinders filled with concrete. Experimental variables include concrete strength, type of fiber, and the ratio of fiber volume to concrete volume.

Delayed failure in rock loaded in uniaxial compression

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1986
The long-term response to sustained compressive loading of two crystalline hard rocks of the Canadian Shield has been investigated. Static fatigue tests conducted on granite and anorthosite have shown that in a humid environment the long-term strengths of these crystalline igneous rocks could be less than 60 percent of their dry instantaneous strengths.

Stress-strain relations for uniaxial loading

Flow, Turbulence and Combustion, 1949
The mathematical expressions for the stress strain relations of metals in uniaxial loading, which have been proposed by Ludwik and Hollomon and find a more general application now, are discussed. It is elucidated that these empirical formulae cannot agree with the essential behaviour of a metal during uniform straining.

Dislocation structure of the magnesium nanocrystal in uniaxial loading

AIP Conference Proceedings, 2016
We report on molecular-dynamics (MD) simulations of compression loading of nanocrystalline magnesium modeled by the embedded-atom method (EAM) potential. It is shown that plastic deformation is by basal slip and (102) twinning. The formation of stable configurations of dislocation grids is observed.

Effects of Cyclic Loading on the Uniaxial Behavior of Nitinol

Journal of Materials Engineering and Performance, 2011
The widespread development and use of implants made from NiTi is accompanied by the publication of many NiTi material characterization studies. These publications have increased significantly the knowledge about the mechanical properties of NiTi. However, this knowledge also increased the complexity of the numerical simulation of NiTi implants or ...

Uniaxial Cyclic Loading of Elastic-Viscoplastic Materials

Journal of Applied Mechanics, 1979
Elastic-viscoplastic constitutive equations based on two internal state variables are utilized to determine material response for uniaxial cyclic loading conditions. These equations are capable of representing the principal features of cyclic loading behavior including softening upon stress reversal, cyclic hardening or softening, tendency toward a ...
