Full-scale testing of stiffened extended shear tab connections under combined axial and shear forces

Owing to the lack of a comprehensive published procedure for the design of stiffened extended shear tabs, practicing engineers usually follow design guides for unstiffened shear tabs. The results of recent laboratory experiments and numerical analyses have ...

Seismic Dispersion and Attenuation in Fluid-Saturated Carbonate Rocks: Effect of Microstructure and Pressure

Lucas Xan Pimienta

The frequency dependence of seismic properties of fully saturated rocks can be related to wave-induced fluid flows at different scales. The elastic dispersion and attenuation of four fluid-saturated carbonate rocks, with different microstructures, have bee ...

Durability of adhesively bonded joints between pultruded GFRP adherends under hygrothermal and natural ageing

Thomas Keller, Joào Pedro Girâo Meireles de Sousa

This paper presents an experimental and numerical study about the durability of adhesively bonded joints between pultruded glass fibre reinforced polymer (GFRP) adherends for civil engineering applications. Single lap joint (SLJ) specimens were manufacture ...

Cell-free soil bio-cementation with strength, dilatancy and fabric characterization

Lyesse Laloui, Dimitrios Terzis

A multi-disciplinary approach is adopted in the present work towards investigating bio-cemented geo-materials which extends from sample preparation, to microstructural inspection and mechanical behaviour characterization. We suggest a new way to induce “ce ...

3D Finite Element Model for Shear Stiffness of Wood-Wood Connections for Engineered Timber Panels

Yves Weinand, Julien Gamerro, Anh Chi Nguyen, Jean-François Bocquet

With the development of automated design and fabrication tools, researchers have shown a growing interest for traditional timber joining techniques. Innovative wood-wood connections, referred to as integral mechanical attachments, have been developed and s ...

Abaqus models and input files for simplified micro models of in-plane loaded masonry walls

Katrin Beyer, Bastian Valentin Wilding, Kiarash Mohtasham Dolatshahi

The data set contains the Abaqus input files of the numerical analyses presented in two research papers. 1) Influence of load history on the force-displacement response of in-plane loaded unreinforced masonry walls, Engineering Structures, 2017, L ...

Micromechanical controls of mixed-mode anticrack nucleation in porous solids: application to snow failure

Johan Alexandre Philippe Gaume, Henning Löwe, Jonas Ritter

Porous cohesive materials can fail and collapse under compressive stresses. This mechanical behavior is generally referred to as anticrack and in snow, it is at the origin of catastrophic avalanches. In this study, we investigate how the microstructure of ...

Analysis of morphological and haemodynamical indexes in abdominal aortic aneurysms as preliminary indicators of intraluminal thrombus deposition

Alfio Quarteroni, Simone Deparis, Claudia Maria Colciago

In this paper we study the correlation between the Wall Shear Stress (WSS), a haemodynamical index derived from numerical simulations, and an new index MFA-ILT for the characterisation of intraluminal thrombus (ILT) in presence of abdominal aortic aneurysm ...

How does seismic anisotropy evolve as a function of mineralogical and textural changes across ductile shear zones? – an experimental and modelling approach

Henri Joseph François Gilles Leclère

Strain localization and the development of ductile shear zones in the middle and lower crust play major roles in lithosphere dynamics. Geophysical imaging of ductile shear zones is an issue for ore geology, for the understanding of the lithosphere rheology ...

Out-of-equilibrium dynamical equations of infinite-dimensional particle systems I. The isotropic case

Elisabeth Agoritsas

We consider the Langevin dynamics of a many-body system of interacting particles in d dimensions, in a very general setting suitable to model several out-of-equilibrium situations, such as liquid and glass rheology, active self-propelled particles, and gla ...
