Change of beam distribution due to decoherence in the presence of transverse feedback

Xavier Buffat, Sondre Vik Furuseth

The effect of Landau damping is often calculated based on a Gaussian beam distribution in all degrees of freedom. The stability of the beam is however strongly dependent on the details of the distribution. The present study focuses on the change of bunch d ...

Systematic investigations of the effects of mechano-electric coupling (MEC) on cellular cardiac electrophysiology lack experimental systems suitable to subject tissues to in-vivo like strain patterns while simultaneously reporting changes in electrical act ...

Ductility, recovery and strain rate dependency of an acrylic structural adhesive

Thomas Keller, Anastasios Vassilopoulos, Myrsini Angelidi

The ductility and time-dependent recovery of a ductile acrylic adhesive were investigated in this work. The quasi-static true tensile and compressive strain behaviors were examined at different strain rates, taking large deformations into account. Yield st ...

Laminated connections for structural glass applications under shear loading at different temperatures and strain rates

Alain Nussbaumer, Pieter Christian Louter, Manuel Santarsiero

Connections between structural glass components represent one of the main critical aspects of glass engineering. In the last years, a novel typology of adhesive connections has emerged, known as laminated adhesive connections. Two adhesive materials for la ...

Elsevier2016

Dynamic and post-dynamic recrystallization kinetics were investigated during hot-working of Inconel 718 as a function of temperature,strain and strain rate in the single phase domain.The post-dynamic evolution was found to be extremely fast and impacting s ...

Behaviour of concrete in compression and shear under varying strain rates: from rapid to long-term actions

Aurelio Muttoni, Miguel Fernández Ruiz, Darko Tasevski

In the present research, the uniaxial compression behaviour of concrete under different strain rates is investigated. The investigation emphasises the influence of the strain rate on the development of inelastic deformations due to nonlinear creep for high ...

Lightning location systems (LLSs) are often used to obtain parameters of lightning flashes. However, the imperfect detection efficiency (DE) of these systems affects the accuracy of the results. In this paper, we focus on the effects of the imperfect DE on ...

We report on the real space profile of spin polarons in the quasi-two-dimensional frustrated dimer spin system SrCu2(BO3)(2) doped with 0.16% of Zn. The B-11 nuclear magnetic resonance spectrum exhibits 15 additional boron sites near nonmagnetic Zn impurit ...

Marginal Stability in Structural, Spin, and Electron Glasses

Matthieu Wyart, Markus Müller

We revisit the concept of marginal stability in glasses and determine its range of applicability in the context of an avalanche-type response to slow external driving. We argue that there is an intimate connection between a pseudogap in the distribution of ...

2D to 3D dynamic fragmentation with parallel cohesive elements

Jean-François Molinari, Nicolas Richart, Marco Vocialta

Dynamic fragmentation is a fast and catastrophic failure that takes place when an extreme load is applied to a material. During this process complex crack patterns develop. Cracks initiate at internal micro-defects, they propagate, eventually branch, and f ...
