This semester project deals with the implementation of the unpreconditioned linear direct solve in C++ as a part of the FEM library Akantu [4] of the Computational Solid Mechanics Laboratory (LSMS) at EPFL. Based on the reference code, a Python re-implemen ...
Earthquakes are a natural hazard affecting millions of people globally every year. Researchers are working on understanding the mechanisms of earthquakes and how we can predict them from various angles, such as experimental work, theoretical modeling, and ...
SEM microfractographies of Zircaloy-4 are studied by fractal analysis and the time-series method. We first develop a computer application that associates the fractal dimension and lacunarity to each SEM micrograph picture, and produce a nonlinear analysis ...
We prove non-uniqueness for a class of weak solutions to the Navier???Stokes equations which have bounded kinetic energy, integrable vorticity, and are smooth outside a fractal set of singular times with Hausdorff dimension strictly less than 1. ...
Situé le long d’un axe urbain important de l’Ouest lausannois et proche du quartier en développement de Malley-Centre, le projet s’inscrit dans un secteur en pleine densification. Celle-ci joue un rôle clé au sein des villes dans la lutte contre l’étalemen ...
This paper presents the historical development of the vertical extensions of unreinforced masonry buildings in the Eixample district of Barcelona and their impact on the seismic behaviour. Existing masonry buildings of Eixample present significant seismic ...
In concrete structures, opened cracks contribute significantly to the transfer of shear and normal stresses through the contact forces occurring between fractured surfaces. Such contact forces are due to protruding asperities, engaged by interlocking and f ...
In the past 20 years, the growing interest in deep geo-reservoirs for purposes such as carbon storage, waste water disposal, or geothermal energy exploitation have led to large-volume fluid injections into the upper continental crust. These fluid injection ...
RILEM TC 267 TRM- "Tests for Reactivity of Supplementary Cementitious Materials" recommends the Rapid Reliable Relevant (R-3) test as a method for determining the chemical reactivity of supplementary cementitious materials (SCMs) in Portland cement blends. ...
This paper presents the manufacturing and the mechanical and thermomechanical properties of a bio-based glass fibre-reinforced polymer (GFRP) composite, produced by vacuum infusion, using an in-house high-performance bio-based unsaturated polyester resin ( ...
