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 new simple model for predicting the uniaxial stress-strain behavior of a unidirectional ceramic matrix composite. including stochastic matrix crack evolution, stochastic fiber damage and ultimate failure, is presented. The model demonstrates an important ...
A new model for predicting the uniaxial stress-strain behavior of a unidirectional ceramic matrix composite, including stochastic matrix crack evolution, stochastic fiber damage, and ultimate failure, is presented. The model shows that (i) "brittle" behavi ...
We report on the first observation of both confined optical phonons and interface phonons in a single strained InAs quantum well grown on InP. Quasi resonant Raman measurements allow for the observation of interface modes. Informations about the mismatch i ...
A comparative study of shaken flask cultures of some yeast strains capable of fermenting lactose showed no significant differences in EtOH [64-17-5] yield among the 4 best strains. Use of whey permeate concd. 3 times did not affect the yields. An optimal g ...
Synchrotron x-ray imaging and stress measurements of diamond-anvil cell gaskets revealed large elastic strains at the diamond tip at a pressure of 300 gigapascals. The diamond, generally considered a rigid body, bent 16 degrees over a distance of 300 micro ...
Traction tests on soft tissues show that the shape of the stress strain curves depends on the strain rate at which the tests are performed. Many of the constitutive models that have been proposed fail to properly consider the effect of the strain rate when ...
The variation of wall stress distribution with age in the thoracic and abdominal aortas of normotensive rats was studied. Dimensions of the zero-stress configurations were measured at the ages of 4, 8, 12, 20, and 52 weeks. Using data from previously publi ...
