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.
This paper examines the mechanisms by which a polymer is dispersed in a co-rotating twin-screw extruder. An experimental investigation of the morphological evolution has been carried out on a 45-mm co-rotating twin-screw extruder. Polyethylene/polystyrene ...
Low-cycle fatigue failure in titanium metal matrix composites is caused by two separate damage mechanisms: fatigue crack growth in the Ti matrix and fiber breakage. Here, a coupled numerical model for predicting both crack growth and fiber breakage is deve ...
Stress changes in hydrogenated phosphorous-doped fibers after Bragg grating inscription have been measured. Fibers with three different drawing tensions have been investigated. The core stress was found to increase independently of the initial stress state ...
The failure of fiber-reinforced ceramic and metal matrix composites under a fixed load for extended times occurs because of strength degradation in the constituent fibers. Specifically, the ceramic fibers possess a Weibull strength distribution caused by c ...
THE MECHANICAL properties of ceramic matrices uniaxially reinforced with strong continuous fibers depend on a wide variety of material parameters: the fiber and matrix elastic moduli, the matrix toughness, the statistical fiber strength, the fiber radius a ...
Strong correlation between index change and stress change in irradiated optical fibers is reported. The stress increases with fluence. Stress changes and hence index changes seem to be due to a compaction of the fiber core ...
Results on fracture, fatigue crack growth and debonding on compact tension specimens of a specially made composite material are reported. The specimens consisted of an epoxy matrix and layers of equally spaced long aligned glass fibers. The experimental da ...
Stretchable optical and electronic fibers constitute increasingly important building blocks for a myriad of applications, particularly in robotics, soft prosthesis, surgical tools and implants, and smart medical textiles. The integration of multimaterial a ...
