iMechanica has over 16,000 registered users
The number of registered users of iMechanica passed 16,000 early today. The the number of posts passed 6,900, and that of comments, 12,500.
iMechanica was founded in September, 2006, with the mission:
- to use the Internet to enhance communication among mechanicians
- to pave a way to evolve online all knowledge of mechanics
I quote what I wrote when the number of registered user passed 1000 in early 2007:
Open Ph.D. position in the area of microbial inactivation mechanics
The Department of Mechanical and Aerospace Engineering at Rutgers University has an open position for a highly-motivated individual in the area of solid and bio mechanics starting January 2010. The scope of the Ph.D. dissertation will be focused on advancing the understanding of the role of mechanical drivers on the mechanisms responsible for bacterial inactivation. This dissertation, supported by the USDA, will be guided by Prof. Alberto Cuitino in collaboration with an interdisciplinary team in microbiology and food science.
Professor Huajian Gao will give the Robert Henry Thurston Lecture at the 2009 ASME International Mechanical Engineering Congress
Professor Huajian Gao, Brown University, will give the Robert Henry Thurston Lecture at the 2009 International Mechanical Engineering Congress, Orlando, Florida. His lecture “Nanomechanics of biological systems - What can we learn from nature about hierarchical materials?” will be in room Euro 10, on the 3rd floor at the Walt Disney Dolphin Hotel (conference hotel), at 10am, November 16, Monday.

Abaqus - simulation non-destructive testing (ultrasonic) - pipe crack
Dear Sir,
My name is Ibraheem. I am a researcher doing my master degree. In my model I am using ABAQUS for simulating a crack detection in a pipe with ultrasonic testing. I have the following software problems:
1- How to implement the acoustic medium with the tested pipe structure using ABAQUS.
2- Which is best:to use for my model shock or the direct solution stedy state dynamic analysis and how can I implement the best of them.
Kuster-Toksoz expressions
Hello ,
I stady the propagation of wave elastic in poroux media and i want to know the Kuster-Toksoz expressions for one spherical inclusion
Thank you
Open PhD position: Inverse identification from full field measurements
The part of full field displacement measurements is increasing in
experimental mechanics. Their taking into account relies on the
development of suited identification approaches, which have to be able
to take advantage of their richness. When dealing with composites, they
offer the possibility to perform the identification at a scale where
the material is heterogenenous. The goal of this thesis is to apply
inverse approaches on the challenging case of the identification of
heterogeneous elasticity and develop a robust identification
Bending and wrinkling as competing relaxation pathways for strained free-hanging films
A thin film subject to compressive strain can either bend (for large strain gradient) or wrinkle (for small strain gradient). The bending is traditionally used in thermostats (bimetal stripes), but couple of years ago, it was extended to the nanoscale thin films which can bend and roll-up to tubes with defined number of rotations. The wrinkles are also rather common in macro- and microscale thin films.
Here, we developed an equilibrium phase diagram for the shape of
compressively strained free-hanging films by total strain energy
minimization.
