Porous materials with two populations of voids under internal pressure: II. Growth and coalescence of voids
This study is devoted to the mechanical behavior of polycrystalline materials with two populations of voids, small spherical voids located inside the grains and larger spheroidal voids located at the grain boundaries. In part I of the work, instantaneous effective stress-strain relations were derived for fixed microstructure. In this second part, the evolution of the microstructure is addressed...
متن کاملInternal Nano Voids in Yttria-Stabilised Zirconia (YSZ) Powder
Porous yttria-stabilised zirconia ceramics have been gaining popularity throughout the years in various fields, such as energy, environment, medicine, etc. Although yttria-stabilised zirconia is a well-studied material, voided yttria-stabilised zirconia powder particles have not been demonstrated yet, and might play an important role in future technology developments. A sol-gel synthesis accomp...
متن کاملCurvature Estimates in Asymptotically Flat Lorentzian Manifolds
We consider an asymptotically flat Lorentzian manifold of dimension (1, 3). An inequality is derived which bounds the Riemannian curvature tensor in terms of the ADM energy in the general case with second fundamental form. The inequality quantifies in which sense the Lorentzian manifold becomes flat in the limit when the ADM energy tends to zero.
متن کاملInconsistency of phylogenetic estimates from concatenated data under coalescence.
Although multiple gene sequences are becoming increasingly available for molecular phylogenetic inference, the analysis of such data has largely relied on inference methods designed for single genes. One of the common approaches to analyzing data from multiple genes is concatenation of the individual gene data to form a single supergene to which traditional phylogenetic inference procedures - e...
متن کاملStrichartz Estimates for the Wave Equation on Flat Cones
We consider the solution operator for the wave equation on the flat Euclidean cone over the circle of radius ρ > 0, the manifold R+ × ( R / 2πρZ ) equipped with the metric g(r, θ) = dr2 + r2 dθ2. Using explicit representations of the solution operator in regions related to flat wave propagation and diffraction by the cone point, we prove dispersive estimates and hence scale invariant Strichartz...
