Graph Chatbot
Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Structural stability issues in planar solid oxide fuel cells (SOFC) arise from the mismatch between the coefficients of thermal expansion (CTE) of the components. The stress state at operating temperature is the superposition of several contributions, whic ...
Nowadays the joining of dissimilar materials is often the only solution to fulfill the complex requirements of high technology applications. One of the fields in which the research activity is more intense and promising is that of the brazing of ceramics w ...
From airplanes to sailboats to bridges, composite materials have become a significant part of our everyday structures. With increasing demand, these materials are pushed to their limits to improve structural efficiency. As a consequence, research and devel ...
The motivation of this work derives from the need of the cutting tool industry to improve its products in order to support harder and harder working conditions, namely increasing cutting speeds and working on stronger modern materials. The lifetime of the ...
The purpose of this thesis is to characterize internal strains in polymeric materials due to consolidation. In view of this, optical Fiber Bragg Grating sensors are an excellent non-destructive tool for internal strain characterization and damage detection ...
The importance of Fibre Reinforced Polymers (FRPs) as a material used for civil engineering purposes has grown in the last decade. Especially the introduction of pultrusion at an industrial level as a way to produce big batches of FRP made it possible to o ...
The deformation mechanisms of silicon {001} surfaces during nanoscratching were found to depend strongly on the loading conditions. Nanoscratches with increasing load were performed at 2 μm/s (low velocity) and 100 μm/s (high velocity). The load-penetratio ...
Particle Reinforced Metal Matrix Composites (PRMMCs) are produced by high-pressure infiltration of ceramic particle beds. Matrix materials are either pure Al or Al-4,5%Cu, and the reinforcement is made either of angular or of polygonal alumina particles. T ...
Various top-down, bottom-up, and hybrid fabrication routes of discontinuous palladium nano and mesostructures can be used for the fabrication of resistor based H2 sensing devices. 1D, 2D, and 3D structures can be achieved using appropriate material templat ...
The relationships between applied stress, deformation and internal pressure of water filled inclusions embedded in soft soils were studied to improve understanding of pore-scale mechanical behavior and towards development of methods for in situ measurement ...
