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.
A probabilistic method for the strength prediction of adhesively bonded double lap joints composed of pultruded GFRP adherends subjected to quasi-static axial tensile loading is presented. The prediction method is based on the experimentally determined mat ...
Fiber-reinforced polymer (FRP) composites offer several advantages in relation to traditional materials, such as high specific strength, good corrosion resistance, low thermal conductivity and rapid component installation. Despite the great potential of th ...
The effect of different curing temperatures (from 20 to 40 °C) on the compressive strength and hydration of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) have been investigated between 3 and 28 days, using the loss on ignition test (LOI) and th ...
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 ...
Force and pressure sensors based on the piezoresistive properties of thick- film resistors have recently found wide application due to their low cost, reliability, and relatively good precision. Achieving high elastic mechanical strains is important to max ...
A new numerical model is proposed for simulating the mechanical behavior of unidirectional composites which is based on a three-dimensional (3D) shear-lag model. The 3D shear-lag model considers the micro-damage phenomena of interfacial debonding and inter ...
At small sizes, piezoelectric bending actuators are more practical and have more favorable downscaling properties than traditional electromagnets in the field of microfluidics. However, their application is limited by the difficulty of ensuring proper clam ...
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 ...
The constitutive response of a Sigma9(221) symmetric tilt grain boundary in copper is investigated with an atomistic quasicontinuum method under tension and shear. The maximum strength is found to change with the deformation mode triggered at the interface ...
A series of 16 specimens of concrete web panels 23.6 x 23.6 x 4.9 in. (600 x 600 x 125 mm) was tested in compression to investigate the effect of the presence of various types of post-tensioning ducts on the strength of the shear-induced compression struts ...
