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 development of a conceptual framework to test different viscoelastic constitutive laws is presented. This framework has the advantage of satisfying a priori the thermodynamic restrictions and is valid for large deformations. In addition, the different ...
AISI 304 and 316 stainless steels of two purity levels that have been irradiated with high energy protons up to 0.3 dpa and neutrons in a high flux reactor up to 7.5 dpa were investigated in terms of irradiation induced mechanical properties and microstruc ...
Plastic deformation of Al-Pd-Mn icosahedral quasicrystals has been achieved at room temperature using a high-confining-pressure medium. The deformation microstructure, investigated by transmission electron microscopy, is characterized by long straight band ...
The microstructural characterization of two titanium alloys, Ti5Al2.5Sn and Ti6Al4V, was performed. These alloys were selected as representatives of the alpha and alpha + beta titanium families, to investigate their possible application as structural mater ...
This paper focuses on the constitutive behavior of the F82H ferritic/martensitic steels internationally investigated in the frame of the fusion material development program. Tensile tests were carried out in the temperature range (80-723 K) at different st ...
The deformed microstructures of both irradiated and unirradiated Fe-9%Cr (Fe-9Cr) uniaxial tensile specimens have been examined to identify controlling mechanisms. Deformation following irradiation is found to occur in poorly defined channels about 100 nm ...
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 mechanical properties of extruded films of isotactic polypropylene (iPP) and ethylene-propylene rubber toughened iPP (iPP/EPR) have been analyzed in terms of the specific essential and non-essential work of fracture using high speed tensile test appara ...
AlPdMn quasi-crystalline specimens were deformed at low temperatures using a high-confining-pressure device. The microstructures, observed in each sample by transmission electron microscopy, depend on the deformation temperature and show that plastic defor ...
A comparison of experimental observations and computer simulations shows that trends in the occurrence and severity of center cracks in direct-chill (DC) cast ingots due to different initial casting speed histories may best be explained by the changes in v ...
