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.
The constant improvement of polymer composite materials has allowed their integration in many industrial fields where their mechanical and chemical properties are apparently attractive. Mixed metal-composite insulators are now increasingly used for high vo ...
The contributions assembled in the present volume proceed from the lectures of the 2009 ALERT Geomaterials School devoted to the Failure in the multiphase geomaterials. The multiphase behaviour of geomaterials used to be mainly considered from the point of ...
The physical mechanisms underlying the dynamic fragmentation of heterogeneous brittle materials are explored through numerical simulations. The use of computational facilities, rather than experimental or fundamental sciences, ensures the accurate tracking ...
Elastoplastic toughness testing of pure aluminium replicated foam is conducted following a J-procedure adapted from the ASTM E1820-08a standard using disc-shaped compact tension specimens. Tests cover a wide range of foam relative density V-m (10-24%). Res ...
Motivated by applications in orthopaedic and maxillo-facial surgery, the mechanical behaviour of cortical bone in cyclic overloads at physiological strain rates is investigated. To this end, a new one-dimensional rate-independent constitutive model for com ...
We present Molecular Dynamics (MD) simulations of the shear–coupled migration behaviour of a Σ 17(530)/[001] symmetrical tilt boundary, in the absence or in the presence of nanocracks lying on the grain boundary (GB) plane. The simulations have been perfor ...
Damage induced by desiccation in clays (i.e. drying shrinkage and cracking) is an issue to be investigated in geo-environmental engineering, especially when the clay is used as a confining barrier for industrial and nuclear waste storage. Dramatic increase ...
Experimental and numerical investigations are carried out on metal/fibregiass-reinforced-plastic joints integrated in electrical insulators subject to bending. Numerical stress and strain distributions through the bond are calculated with a solid 3D finite ...
Damage induced by desiccation (i.e. drying shrinkage and cracking) is an issue to be investigated in deep geological nuclear waste storage engineering. A dried and cracked zone can form in the underground gallery host shale due to ventilation effects. Incr ...
This paper presents the results of a comprehensive experimental study of the desiccation of fine-grained soils. Air-drying of initially saturated soil slabs in controlled conditions is investigated, by performing three kinds of tests: free desiccation test ...
