Exploring the potential of the critical shear crack theory for reinforced and post-tensioned glass beams: Initial analysis and experiments

Alain Nussbaumer, Pieter Christian Louter, Jagoda Cupac

In the evolution of structural glass beam elements, the requirements for post-fracture load bearing capacity and safe failure behaviour have led to the development of reinforced and post-tensioned beams. Maximum bending capacity in the post-fracture state ...

Fractal-like Mechanical Resonators with a Soft-Clamped Fundamental Mode

Tobias Kippenberg, Sergey Fedorov, Alberto Beccari, Nils Johan Engelsen

Self-similar structures occur naturally and have been employed to engineer exotic physical properties. We show that acoustic modes of a fractal-like system of tensioned strings can display increased mechanical quality factors due to the enhancement of diss ...

Extension of Winkler’s solution to non-isothermal conditions for capturing the behaviour of plane geostructures subjected to thermal and mechanical actions

Lyesse Laloui, Qazim Llabjani, Alessandro Francesco Rotta Loria, Jacopo Zannin

Before this study, no analytical models had been made available for describing the behaviour of plane geostructures subjected to thermal and mechanical actions. This knowledge gap notably represented a limitation for investigations about the behaviour of s ...

Two-Tone Optomechanical Instability and Its Fundamental Implications for Backaction-Evading Measurements

Tobias Kippenberg, Amir Youssefi, Liu Qiu, Itay Shomroni

While quantum mechanics imposes a fundamental limit on the precision of interferometric measurementsof mechanical motion due to measurement backaction, the nonlinear nature of the coupling also leads toparametric instabilities that place practical limits o ...

Twist-Induced Snapping in a Bent Elastic Rod and Ribbon

Tomohiko Sano

Snapping of a slender structure is utilized in a wide range of natural and manmade systems, mostly to achieve rapid movement without relying on musclelike elements. Although several mechanisms for elastic energy storage and rapid release have been studied ...

Emergence of Cracklike Behavior of Frictional Rupture: The Origin of Stress Drops

Jean-François Molinari, Thibault Didier Roch, Fabian Barras

The process of frictional rupture, i.e., the failure of frictional systems, abounds in the technological and natural world around us, ranging from squealing car brake pads to earthquakes along geological faults. A general framework for understanding and in ...

Application of multiphysics model order reduction to doppler/neutronic feedback

Carlo Fiorina

In this paper, a proper orthogonal decomposition based reduced-order model is presented for parametrized multiphysics computations. Our application physics is Doppler feedback in a simplified model of the molten salt fast reactor concept. The reduced model ...

CFD as an Enginer's Tool for Investigation of Large-Scale-Flow-Phenomena "at Land, Sea and Air"

Michel Deville

Along with prospective fashion of solving the engineering-tasks (if development would allow us a such approach while answering the technology-questions of some project in future), goes alternatively corrective performance of those engineering tools, used t ...

Breaking Lorentz reciprocity to overcome the time-bandwidth limit in physics and engineering

Hatice Altug, Kosmas Tsakmakidis

A century-old tenet in physics and engineering asserts that any type of system, having bandwidth Delta omega, can interact with a wave over only a constrained time period Delta t inversely proportional to the bandwidth (Delta t-Delta w similar to 2 pi). Th ...
