Identification of cyclic and anisotropic behaviour of ODS steels tubes

In this paper, an elastic plastic behaviour model based on internal state variables is investigated. The final aim is to describe the mechanical stress-strain cyclic response of oxide dispersion strengthened (ODS) steels during the cold pilgering process. ...

Linking Discrete Dislocations and Molecular Dynamics in 3D: a Start

Jean-François Molinari, William Curtin, Guillaume Anciaux, Till Junge

Many phenomena in crystalline metals such as friction, nano-indentation and ductile fracture are plasticity-driven and poorly understood. The physical complexity is further increased by the inherently multiscale nature of contact and fracture [1]. This stu ...

Non-axis-symmetrical punching shear around internal columns of RC slabs without transverse reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz, Juan Sagaseta Albajar, Luca Tassinari

Most analytical approaches and available test data for punching shear in flat slabs assume axis-symmetrical conditions, which seems realistic for representing slabs supported on columns equally spaced in both orthogonal directions. However, in practice, th ...

Biomechanics of Vascular Wall

Rana Saitta-Rezakhaniha

This thesis contributes to the field of biomechanics of vascular wall. The focus is particularly on the microstructure of vascular elastin and collagen constituents and their contribution to the macroscopic mechanical behavior of the wall. The analysis is ...

High-order accurate thin layer approximations for time-domain electromagnetics, Part II: Transmission layers

Jan Sickmann Hesthaven

We continue the development of high-order accurate thin layer approximations for time-domain electromagnetics and focus in this paper on a new family of models for thin transmission layers. The thin transmission layer approximations are valid for general i ...

Analyse non-linéaire des coques géodésiques multicouches à joints semi-rigides

Julius Natterer

In the 90ies the IBOIS-EPFL developed a new kind of shell structure. The ribs were made with simple boards waved together to form a spatial rib shell. However, the engineer currently does not have any effective method to calculate these kinds of spatial st ...

Fracture of high volume fraction ceramic particle reinforced aluminium under multiaxial stress

Andreas Mortensen, Andreas Rossoll, Aude Hauert

Circumferentially notched cylindrical bars of high volume fraction Al2O3 particle reinforced aluminium are tested in tension to probe the role of tensile stress triaxiality on damage and failure of such materials. The transverse strain is monitored with a ...

A three-dimensional elastic plastic damage constitutive law for bone tissue

Alain Curnier

Motivated by mechanical analysis of bones and bone-implant systems, a 3D constitutive law describing the macroscopic mechanical behaviour of both cortical and trabecular bone in cyclic (not fatigue) overloads is developed. The proposed model which mathemat ...

High-order accurate thin layer approximations for time-domain electromagnetics. Part I: General metal backed coatings

Jan Sickmann Hesthaven

We present a family of high-order accurate thin layer approximations for time-domain electromagnetics. The thin layer approximations are valid for metal backed coatings of general isotropic materials and certain classes of anisotropic materials on smooth c ...

Mechanoelectric feedback in cardiomyocyte monolayers and whole hearts in response to stretch

Barbara Murienne

Stretch has been shown to induce electrophysiological changes in the whole heart and cardiomyocyte monolayer models. However, the mechano-electric mechanisms responsible for these changes are still not completely understood. In this project, micropatterned ...
