finite element methods

I would like to share our recent paper "Delayed detached eddy simulation-based aerothermoelastic analysis of deployable control fin in supersonic and hypersonic flows" published in Physics of Fluids. In this paper we study the stability and mechanics of a deployable control fin in supersonic and hypersonic flows accounting for fluid-structure interactions and joint freeplay nonlinearity.

https://doi.org/10.1088/1402-4896/aab4e2 In the 50 years that succeeded Richard Feynman’s exposition of the idea that there is "plenty of room at the bottom" for manipulating individual atoms for the synthesis and manufacturing processing of materials, the materials-by-design paradigm is being developed gradually through synergistic integration of experimental material synthesis and characterization with predictive computational modeling and optimization.

Helices are ubiquitous building blocks in natural and engineered systems. Previous studies showed that helical ribbon morphology can result from anisotropic driving forces and geometric misorientation between the principal axes of the driving forces and the geometric axes. However, helical ribbon shapes induced by elastic modulus anisotropy have not been systematically examined even though most natural and engineered structures are made of composite materials with anisotropic mechanical properties.

Dear all,

Combining
soft active hydrogels with hard passive polymers gives rise to all-polymer
composites. The hydrogel is sensitive to external stimuli while the passive
polymer is inert. Utilizing the different behaviors of two materials subject to
environmental variation, for example temperature, results in self-folding soft
machines. We report our efforts to model the programmable deformation of
self-folding structures with temperature-sensitive hydrogels. The self-folding
structures are realized either by constructing a bilayer structure or by
incorporating hydrogels as hinges. The methodology and the results may aid the

The Summer School on Advances in Finite Element Methods will be held in Cape Town, South Africa, from 14-18 Jan 2013.
The website www.fesummerschool.co.za contains details such as registration, accommodation, lecturers and the schedule. 

The objective of this summer school is first, to provide the necessary background in the mathematics of finite elements, and second, to build on this background by addressing the topics of adaptivity and discontinuous Galerkin methods.

Pressurized elastic capsules arise at scales ranging from the 10 m diameter pressure vessels used to store propane at oil refineries to the microscopic polymeric capsules that may be used in drug delivery. Nature also makes extensive use of pressurized elastic capsules: plant cells, bacteria and fungi have stiff walls, which are subject to an internal turgor pressure. Here, we present theoretical, numerical and experimental investigations of the indentation of a linearly elastic shell subject to a constant internal pressure.

Can you define FEM in one line?

If yes, what would it be? And, in that case, permit me a second question: How?

...Really interested in knowing what the members of this community think (of this matter), if they do...
