Resumen
Ni-base superalloys are widely used in hot sections of gas turbine engines due to the high resistance to fatigue and creep at elevated temperatures. Due to the demands for improved performance and efficiency in applications of the superalloys, new and improved higher temperature alloy systems are being developed. Constitutive relations for these materials need to be formulated accordingly to predict behavior of cracks at notches in components under cyclic loading with peak dwell periods representative of gas turbine engine disk materials. Since properties are affected by microstructure at var

Resumen
The mechanical and physical properties of polymers are determined primarily by the underlying nano-scale structures and characteristics such as entanglements, crystallites, and molecular orientation. These structures evolve in complex manners during the processing of polymers into useful articles. Limitations of available and foreseeable computational capabilities prevent the direct determination of macroscopic properties directly from atomistic computations. As a result, computational tools and methods to bridge the length and time scale gaps between atomistic and continuum models are requ

Resumen
Resin infusion-based processes are good candidates for manufacturing thin composite materials parts such as those used in aeronautics for instance. These processes consist in infusing a liquid resin into a stacking of fibrous preforms under the action of a mechanical pressure field applied onto this stacking where a stiff- distribution medium is also placed to create a resin feeding. Both physical and mechanical properties of the final pieces are rather difficult to predict and control. Numerical simulation are perfectly suited to master these processes.

Resumen
Le domaine intracontinental est éloigné des limites des plaques tectoniques sur lesquelles sont localisées l’essentiel des déformations. La déformation intraplaque est une conséquence de la transmission de la contrainte depuis les limites de plaques vers le domaine intraplaque. Elle peut s’exprimer par un flambage lithosphérique, par des déformations régionales et des réseaux de fractures à micro- et méso-échelle. Ces déformations reflètent la nature des régimes de contraintes aux limites des plaques continentales. Elles ont une distribution hétérogène et à l'échelle régionale, révèlent souven

Resumen
Superplastic forming (SPF) is a valuable near net shape fabrication method, used to produce very complex, contoured and monolithic structures that are often lighter, stronger and safer than the assemblies they replace. However, the widespread industrial use of Superplastic (SP) alloys is hindered by a number of issues including low production rate and limited predictive capabilities of stability during deformation and failure. Failure during SPD may result from geometrical macroscopic instabilities and/or microstructural aspects. However, the available failure criteria are either based on geom

Le deformazioni lente di versante in roccia (DGPV e grandi frane) sono fenomeni diffusi che interessano interi versanti e mobilizzano volumi di roccia anche di miliardi di metri cubi.

Sebbene caratterizzate da bassi tassi di spostamento (fino a pochi cm / anno), queste instabilità di versante danneggiano infrastrutture e ospitano settori potenzialmente soggetti a differenziazione e collasso catastrofico.

By utilising this novel modelling approach, the distinct deformation profiles of several food-plant materials were revealed along with the impact of drying situations and features in the microstructure.

However, the strength and toughness of CP titanium are affected by relatively small variations in their impurity/solute content (IC), e.g., O, Al, and V. This increase in strength is due to the fact that the solute either increases the critical stress required for the prismatic slip systems ({10-10}<1-210>) or activates another slip system ((0001)<11-20
