Accounting for geometric nonlinearity in finite element strength calculations of thin-walled shell-type structures

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2020
Relevance. Currently, in connection with the wider spread of large-span thinwalled structures such as shells, an urgent issue is the development of computational algorithms for the strength calculation of such objects in a geometrically nonlinear ...

Significantly improving strength and plasticity of Al-based composites by in-situ formed AlCoCrFeNi core–shell structure

open access: yesJournal of Materials Research and Technology, 2021
The mechanical properties of Al matrix composites reinforced by AlCoCrFeNi high entropy alloy particles were greatly enhanced after spark plasma sintering at 600 °C accompanied with the formation of reinforcement core–shell structure.

Scaling and Dissipation in the GOY Shell Model [PDF]

open access: yes, 1994
This is a paper about multi-fractal scaling and dissipation in a shell model of turbulence, called the GOY model. This set of equations describes a one dimensional cascade of energy towards higher wave vectors.

Multiscaling in superfluid turbulence: A shell-model study

open access: yes, 2015
We examine the multiscaling behavior of the normal- and superfluid-velocity structure functions in three-dimensional superfluid turbulence by using a shell model for the three-dimensional (3D) Hall-Vinen-Bekharevich-Khalatnikov (HVBK) equations.

Nuclear shell evolution and in-medium NN interaction [PDF]

open access: yes, 2012
We report on a quantitative study of the evolution of the nuclear shell structure, in particular, effective single-particle energies (ESPEs), based on the spin-tensor decomposition of an effective two-body shell-model interaction.
