Modelling of the Cyclic Response of an Unreinforced Masonry Wall through a Force Based Beam Element

Katrin Beyer, Francesco Vanin, João Saraiva Esteves Pacheco de Almeida

The seismic assessment of existing masonry buildings is based on the prediction of their nonlinear response under lateral loading. This requires a reliable estimation of the force and displacement demand. For this purpose, modelling strategies using struct ...

Hard-sphere displacive model of deformation twinning in hexagonal close-packed metals. Revisiting the case of the (56, a) contraction twins in magnesium

Cyril Cayron

Contraction twinning in magnesium alloys leads to new grains that are misoriented from the parent grain by a rotation (56°, a). The classical shear theory of deformation twinning does not specify the atomic displacements and does not explain why contractio ...

Experimental validation of a railway bridge made of a reinforced UHPFRC-T-beam

The material UHPFRC is not yet used in the field of bridge construction regularly. The reasons are missing codes and allurements for innovation in the structural engineering. Nevertheless, UHPFRC has many advantages, which are significant compared to the u ...

Effect of fluid viscosity on fault frictional behavior

Marie Estelle Solange Violay, Chiara Cornelio

Tectonic faults are often lubricated by viscous fluids which can have different natures e.g. gas, water, brine, melt and viscosities varying over 7 order of magnitude (from 10-4 for water to 103 Pa s-1 for a melt at high temperature). Moreover, understandi ...

Velocity shear, turbulent saturation, and steep plasma gradients in the scrape-off layer of inner-wall limited tokamaks

Paolo Ricci, Federico David Halpern

The narrow power decay-length (lambda(q)), recently found in the scrape-off layer (SOL) of inner-wall limited (IWL) discharges in tokamaks, is studied using 3D, flux-driven, global two-fluid turbulence simulations. The formation of the steep plasma profile ...

Stokes' third problem for Herschel-Bulkley fluids.

Christophe Ancey, Belinda Margaret Bates

Herschel-Bulkley materials can be set in motion when a sufficiently high shear stress or body force is applied to them. We investigate the behaviour of a layer of Herschel-Bulkley fluid when it is suddenly tilted and subject to gravitational forces. The ma ...

Shear in reinforced concrete without transverse reinforcement

Francesco Cavagnis

Since the first applications of structural concrete, the shear behaviour of one-way slabs without transverse reinforcement has been largely investigated. Nevertheless, currently in the scientific community there is no general agreement on the mechanisms of ...

Outer midplane scrape-off layer profiles and turbulence in simulations of Alcator C-Mod inner-wall limited discharges

Federico David Halpern

A region of steep plasma gradients, the so-called "narrow-feature," has been found in the near scrape-off layer (SOL) of inner-wall limited (IWL) discharges. Dedicated IWL discharges were carried out in Alcator C-Mod [Marmar et al., Nucl. Fusion 55, 104020 ...

This thesis has been put in place during the development of an innovative medical device which consists in an intelligent footwear for foot plantar pressure redistribution in diabetic patients. In fact, despite the several sophisticated techniques develope ...

EXPERIMENTAL RESULTS ON SEDIMENT ENTRAINMENT BY GRAVITY CURRENTS

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez, Jessica Zordan

Gravity currents are geophysical flows responsible of the distal transport of high volumes of sediments. In particular, turbidity currents, a form of gravity currents where sediments in suspension confer the buoyancy that ignites the flow, are the main mec ...
