High resolution measurements of mechanical properties of the constituent phases of multi-phase materials are of immerse importance in design of new composites. In this study, the nanoindentation, X-ray analysis and microstructural SEM investigations have been used to reveal the properties and structural features of ceramic – metal composites involv...
Understanding the nature of the physical properties of lithic raw materials is a pre-requisite for developing more reliable interpretations of use-wear evidence and tool function. We use nanoindentation and use-wear experimentation as a way to measure differences in raw material surface hardness and roughness in order to show that differences in li...
Most studies of effective properties of random heterogeneous materials are based on the assumption of the existence of a representative volume element (RVE), without quantitatively specifying its size L relative to that of the micro-heterogeneity d. In this paper, we study the finite-size scaling trend to RVE of the Darcy law for Stokesian flow in...
Under consideration is the finite-size scaling of effective thermoelas- tic properties of random microstructures from a Statistical Volume Element (SVE) to a Representative Volume Element (RVE), without invoking any pe- riodic structure assumptions, but only assuming the microstructure's statistics to be spatially homogeneous and ergodic. The SVE i...
High-resolution measurements of mechanical properties of composites produced by powder metallurgy techniques are of immerse importance for reliable materials production. Measuring the intrinsic properties of each phase separately in multiphase composites gives the information on the spatial heterogeneity in local material properties and serves as a...
A computational fluid dynamic (CFD) study analyzing wind effects on natural draft dry cooling towers was conducted. In the CFD study, a full scale dry cooling tower with en-vironment domain was modeled. The atmospheric boundary layer and thermally driven cooling tower flows were simulated. Reynolds-averaged Navier–Stokes (RANS) turbulence model was...
