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.
Toughness measurements of a Ti-45Al-2N4u-2Nb + 0.8%vol TiB2 alloy with a. near fully lamellar microstructure and a Ti-46Al-8Nb alloy with a convoluted microstructure are performed at 650 degrees C under vacuum according to ASTM Standard E1820. Respective v ...
In this study, the tensile and fracture properties and the microstructure of the reduced-activation tempered martensitic steel Eurofer97 have been investigated. This technical alloy is a 9%Cr steel developed within the European fusion material research pro ...
The possibility of decreasing ultimate tensile strength associated with increasing fiber/matrix interfacial sliding is investigated in ceramic-matrix composites. An axisymmetric finite-element model is used to calculate axial fiber stresses versus radial p ...
A new technique using prestressed carbon fiber laminates (CFRP – Carbon Fiber Reinforced Polymers) is being developed to repair fatigue cracks or prevent fatigue cracking on riveted bridge members. High fatigue resistance and high tensile strength of carbo ...
Reinforced concrete slabs supported on columns fail by punching when a conical plug of concrete perforates the slab above the column. This failure has been mostly investigated experimentally, so what can numerical simulation contribute to understand this p ...
Virtual tensile experiments on cylindrical copper wires of nanometric diameter were carried out using molecular dynamics techniques based on the embedded-atom method. Transverse, atomically sharp surface cracks with circular fronts of different depths are ...
Viscoelasticity and crack growth govern the long-term deformability of concrete and thus its service behaviour and its durability. For low load levels, viscoelasticity behaves quasilinearly and crack growth is inactive. On the other hand, for high load lev ...
A method based on microindentation is developed to determine the fracture toughness K-1c of a thin film bonded to a brittle substrate. Using an easily fabricated sample having a partially coated substrate, indentation on the uncoated portion of the substra ...
Ultra High Performance Fiber Reinforced Concretes (UHPFRC) present outstanding mechanical properties and a very low permeability. Those characteristics make them very attractive for the rehabilitation of existing structures and the conception of new struct ...
The primary mission of the international fusion material irradiation facility (IFMIF) is to generate a material database to be used for the design of various components, for the licensing and for the assessment of the safe operation of a demonstration fusi ...
