We evaluate the percolation threshold values for a realistic model of continuum segregated systems, where random spherical inclusions forbid the percolating objects, modeled by hardcore spherical particles surrounded by penetrable shells, to occupy large regions inside the composite. We find that the percolation threshold is generally a nonmonotonous function of segregation, and that an optimal...
The mixing of cold, high-density shell plasma with the low-density, hot spot plasma by the Rayleigh-Taylor instability in inertial confinement fusion is experimentally shown to correlate with the calculated perturbation feedthrough from the ablation surface to the inner shell surface. A fourfold decrease in the density of shell material in the mix region of direct drive implosions of gas filled...
Rotation is a general phenomenon in astrophysical systems on scales from planets to giant galaxy clusters. It is established during the formation of the system under gravitational compression. Typically the rotation rate is greatly enhanced during this process (Thompson et al. 2003). Rotation of stars defines their shapes and drives the internal circulation which redistributes chemical elements...
Abstract We investigate norms of spectral projectors on thin spherical shells for the Laplacian tori. This is closely related to boundedness resolvents and $L^{p}$ eigenfunctions Laplacian. formulate a conjecture partially prove it.
In this article, the prominence has been given to study the influence of skew angle on bending response of functionally graded material shell panels under thermo-mechanical environment. Derivation of governing equations is based on the Reddy’s higher-order shear deformation theory and Sander’s kinematic equations. To circumvent the problem of C1 continuity requirement coupled with the finite el...
Emergence of new technological applications, in addition to the constantly growing interest in biological materials has accentuated the importance of studying the mechanics of highly deformed shells. The key challenge is the intricate interplay of physics and geometry, which leads to a mechanical response much different from the response of solid objects. The quest to understand the underlying ...
