Employing mesh segmentation algorithms as fabrication strategies: Pattern generation based on reaction-diffusion mechanism [PDF]

open access: yesFME Transactions, 2019
This paper examines how the evolution of architectural generative design processes aim to apply similar physical and geometrical principles of biological processes taking place during development and to translate them to fabrication processes. In analogy

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 ...

Research on seismic performance of honeycomb plate cylindrical reticulated shell structure

open access: yesCase Studies in Construction Materials, 2023
In previous research, an aluminum alloy honeycomb plate cylindrical reticulated shell structure was designed. The bearing capacity test and numerical analysis show that the numerical analysis model of honeycomb plate cylindrical reticulated shell ...

Classcial Bifurcation and Enhancement of Quantum Shells --- Systematic Analysis of Reflection-Asymmetric Deformed Oscillator --- [PDF]

open access: yes, 1995
Correspondence between classical periodic orbits and quantum shell structure is investigated for a reflection-asymmetric deformed oscillator model as a function of quadrupole and octupole deformation parameters.

PHYSICAL STRUCTURE OF SHELL MEMBRANES [PDF]

open access: yesJournal of General Physiology, 1948
The results obtained in the present work bring out clearly that the dried shell membrane is an open lattice-like network containing micropores of the order of 1 micron in mean equivalent diameter and whose surface density is roughly 20 millions per sq. cm.

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.

On the thin-shell limit of branes in the presence of Gauss-Bonnet interactions

open access: yes, 2003
In this paper we study thick-shell braneworld models in the presence of a Gauss-Bonnet term. We discuss the peculiarities of the attainment of the thin-shell limit in this case and compare them with the same situation in Einstein gravity. We describe the

The nuclear shell effects near the r-process path in the relativistic Hartree-Bogoliubov theory [PDF]

open access: yes, 2002
We have investigated the evolution of the shell structure of nuclei in going from the r-process path to the neutron drip line within the framework of the Relativistic Hartree-Bogoliubov (RHB) theory.
