LiveScience is a pretty cool initiative targeted to the general public,
specially the younger generations to communicate the impact and
value of science and the people around it.
Hi dear
I am going to model a 3d dental bridge in abaqus that it is made of 2 parts:
1: a beam with 5 plys from fiber and adhesive (composite part)
2: orthotropic ceramic part which surround the composite beam
I'd appreciate if you help me and write the sequences in the modeling of this issue.
please send it to my email: kian32m [at] yahoo.com (kian32m[at]yahoo[dot]com)
thank
Mechanical energy can be converted to electrical energy by using a dielectric elastomer generator. The elastomer is susceptible to various modes of failure, including electrical breakdown, electromechanical instability, loss of tension, and rupture by stretch. The modes of failure define a cycle of maximal energy that can be converted. This cycle is represented on planes of work-conjugate coordinates, and may be used to guide the design of practical cycles.
The question was raised in class as to what the appropriate equilibrium condition for a column of fluid at rest should be. Specifically, given we expect a hydrostatic gradient in pressure with height, whether the chemical potential must be the same throughout the column was questioned. Here are my first thoughts. In brief, I assert that the chemical potential must be everywhere identical, and that the pv term is balanced, at every height in the column, by the potential energy conferred by position in a gravitational field.
Dear colleagues,
I would like to bring to your attention the advanced course on Modeling of localized inelastic deformation that will be taught by Milan Jirasek in Prague, Czech Republic on 14-18 September 2009.
More detailed information on the course is posted at http://mech.fsv.cvut.cz/~milan/course2009.html. We are looking forward to seeing you in Prague!

Hi,
I am a PhD student at Brunel University conducting my research on the noise and vibration attributed to spur gears in contact. I would like to ask for help from anyone who is an expert on gears for their opinion or direction in terms of reading material or thoughts on the limitations and design constraints of spur gear geometry.
There are three elliptical holes in the given plate, but make different angle with the direction of stress applied on the plate. I wonder if I can gain the solution listed below using analytical methods?(1) crack initiation will happen in which ellipse firstly, (2)the exaxt crack initiation location around the ellipse? And how?
thanks a lot!
I have a 3D model in Abaqus of a wind turbine rotor, modelled with shell elements (S4R and S3). To use the same blade in an aeroelastic wind turbine code (HAWC2 from Risoe), I want to convert selected cross sections of the 3D model to Timoshenko beam elements.
In a previous post some months ago (see here), I mentioned some of the questions I had considering the aeroelastic response of a wind turbine rotor. In this post I just want to give, for those interested, a brief status report.
