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 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
Nonlinear Buckling of Cylindrical Tubes w/ ANSYS
Choose a channel featured in the header of iMechanica
Hi all,
I'm trying to run a nonlinear (elastic for now) buckling analysis in ANSYS. Basically I have a thin cylindrical shell (made up of SHELL181). fixed at one end (rigid) and applied force and/or displacement specified on the other end to make it buckle.
I have pretty much tried all options. These were:
i) Linear buckling (Eigenbuckling)
ii) Displacement controlled buckling with a lateral point force to provide eccentricity/imperfection.
iii)Force controlled buckling with, again, a lateral point force (arc-length method)
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.
