Harnessing uniaxial tension to tune Poisson's ratio and wave propagation in soft porous phononic crystals: an experimental study.

Soft Matter, 2019
Exerting mechanical loads on soft periodic porous phononic crystals provides a unique opportunity to control the propagation of waves through the peculiar band gaps. However, it is quite difficult to experimentally confirm the band gaps in soft materials

Uniaxial concrete tension damage evolution using acoustic emission monitoring

, 2020
The tension damage function is an important component in concrete constitutive models. However, it is difficult to experimentally establish the complete tensile response due to the brittle behavior of concrete.

Plastic instability in uniaxial tension tests

Acta Metallurgica, 1981
Abstract The criterion for plastic instability presented by Hart [1] is shown to apply to both geometrical and deformation defects in a tensile specimen. A first order differential equation is presented to describe strain gradients in a tensile specimen with nonuniform cross-section.

Ordering and Crystallization of Entangled Polyethylene Melts under Uniaxial Tension: A Molecular Dynamics Study

Macromolecules, 2018
Morphological and mechanical properties of semicrystalline polymers are strongly influenced by flow-induced crystallization during processing. We perform extensive molecular dynamics simulations with more than 1 million atoms to describe orientation ...

Uniaxial tension and cyclic tension-compression testing of ceramics

Journal of the European Ceramic Society, 1991
Abstract Two loading and gripping systems for the uniaxial testing of ceramics in tension-creep and in cyclic tension-compression respectively, are presented. In both systems flat samples are held in hydraulic grips (cold gripping). The tensile set-up incorporates an adjustable universal joint in the loading train in order to minimize the bending ...

Deformation of rocks under uniaxial tension

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1973
Abstract Tensile tests were conducted on cylindrical rock specimens, cemented to end-caps attached to non-twist cables. In other tests the rock specimens were bonded to platens cycled between tension and compression. The results indicated that the initial tangent modulus of rock is similar, both in uniaxia tension and in compression, but in tension ...

Plasticity of borosilicate glasses under uniaxial tension

Journal of the American Ceramic Society, 2020
Abstract The mechanical response of multicomponent borosilicate glasses has drawn significant attention in the design of damage‐resistant glasses. In this work, we investigate the plasticity of two borosilicate glasses, Borofloat ® 33 (Boro33) and N‐BK7 ®

Nonlinear viscoelastic properties of human dentin under uniaxial tension

Dental Materials, 2021
Dentin is a viscoelastic tissue that contributes to the load distribution in human teeth and leads to their fracture resistance. Despite previous researches on the time-dependent behavior of dentin, it is not very clear whether the viscoelastic behavior of this tissue is linear or nonlinear, and what viscoelastic constitutive equations mechanically ...

Necking in uniaxial tension

International Journal of Mechanical Sciences, 1983
Abstract Applying two theories in plasticity (flow theory and a modified deformation theory), the necking of a cylindrical bar in uniaxial tension is analysed. The development of finite strain in the bar is handled by the up-dated Lagrangian description and the governing variational equation is solved by using a finite-difference discretization in ...
