MechTube - applied mechanics outreach for children

Submitted by Zak Stone on

Hello everyone,

Professor Suo suggested that I share this speculative idea that I once posted on Applied Mechanics News here on iMechanica!

In the future, we would like to reach out to children as early as their elementary school years to get them excited about topics drawn from Applied Mechanics. One approach to this goal takes inspiration from the successful "Le main a la pate", or "hands-in-dough", program in France (http://www.lamap.fr/ ), but extends the idea of hands-on science to take advantage of the internet.

Master of Science in Mechatronic Systems Engineering

Submitted by Vladimir Vantsevich on

Lawrence Technological University has introduced a new master’s degree program in mechatronic systems engineering, a philosophical approach that cuts across multiple scientific disciplines.

Mechatronic systems engineers design enhanced products, systems and manufacturing processes by bringing together knowledge from mechanical engineering, electrical engineering and computer science. Students learn new principles for designing mechanical subsystems to satisfy control requirements.

Intracellular CalciumWaves in Bone Cell Networks Under Single Cell Nanoindentation

Submitted by Ed Guo on

In this study, bone cells were successfully cultured into a micropatterned network with dimensions close to that of in vivo osteocyte networks using microcontact printing and self-assembled monolyers (SAMs). The optimal geometric parameters for the formation of these networks were determined in terms of circle diameters and line widths. Bone cells patterned in these networks were also able to form gap junctions with each other, shown by immunofluorescent staining for the gap junction protein connexin 43, as well as the transfer of gap-junction permeable calcein-AM dye.

CFRAC 2007 International Conference on Computational Fracture and Failure of Materials and Structures

Submitted by Nicolas MOES on

If you are interested by the computational aspects of fracture and failure of materials and structures,there is a dedicated conference for you : CFRAC 2007, which will be held in Nantes, France, 11-13 June 2007. It is an thematic conference of the European Community in Computational Methods in Applied Sciences (ECCOMAS). The for abstract is now closed. This conference wil involve a certian number

No need to worry about gravity at the atomic-/nano-scale

Submitted by Zhenyu Zhang on

When a metal is grown onto a substrate of itself (homoepitaxy), the growth front is typically smooth, or at most is roughened by the formation of shallow hills (called surface mounds). The underlying reason for the roughening has been recognized to be of kinetic nature: Atoms landed on an upper terrace do not have enough time to overcome the "road blocks" provided by the steps and fill all the valleys (known as the Villian instability).

EFG Matlab Routines

Submitted by John E. Dolbow on

These used to be hosted at Northwestern, but the files were taken down some time ago. The original 1d and 2d Matlab routines for the element-free Galerkin method are now located at

http://www.duke.edu/~jdolbow/EFG/programs.html

These routines are described in detail in the paper
