Today, thanks in particular to the results of ESA Planck mission, concordance cosmological model appears be most robust describe evolution and content Universe from its early late times. It summarizes matter, made mainly dark primordial fluctuations generated by inflation around $10^{-30}$ second after Big-Bang galaxies clusters galaxies, 13.8 billion years later, expansion space, with a relati...

When testing multi-story structures on a shaking table, most testing facilities require a reduced scale model. Producing scale test units at small scale is particularly challenging for unreinforced masonry structures. Previous work by other researchers showed that scaling of units and mortar joints is mandatory in order to obtain for the reduced scale masonry failure modes, which are similar to...

We are interested in the homogenization of elastic-electric coupling equation, with rapidly oscillating coefficients, in periodically perforated piezoelectric body. We justify the two first terms in the usual asymptotic development of the problem solution. For the main convergence results of this paper, we use the notion of two-scale convergence. A two-scale homogenized system is obtained as th...
