In the attached paper, we construct new generalized coordinates for arbitrary polytopes in d-dimensions (polygons and polyhedra in 2- and 3-dimensions, respectively) using the principle of maximum entropy. The paper is to appear in Computer Graphics Forum and will be presented at the SGP'08 Conference in Denmark.
I stumbled across this interesting blog post yesterday concerning an upcoming course on medicine via web 2.0. It appeared quite interesting from several perspectives: first, medicine is often associated with being behind the times on technology but this all looks pretty current, secondly it may be the most comprehensive listing of topics I have seen where web 2.0 is applied to a single discipline, and finally it made me wonder what more we could do with mechanics via web 2.0 beyond just the
We have recently studied the atomic scale structural stability of
freestanding wavy gold (Au) nanofilms using molecular dynamics
simulations. In recent years, wavy or patterned structurs have shown great promise for applications in various emerging technologies including fuel cells
engineering, tissue engineering, biomedical engineering, creation
of counterfeit-resistant documents , nanolithography in microelectronics, optoelectronics, nanomachinesand many others. It is out of question that the success of these novel applications lies on one crucial factor – the
This paper studies the invariance of balance of
energy for a system of interacting particles under groups of
transformations. Balance of energy and its invariance is first
examined in Euclidean space. Unlike the case of continuous media,
it is shown that conservation and balance laws do not follow
from the assumption of invariance of balance of energy under
time-dependent isometries of the ambient space. However, the
postulate of invariance of balance of energy under arbitrary
diffeomorphisms of the ambient (Euclidean) space, does yield
High Performance Computing MSc+Ph.D. position available at the University of Glasgow on Massively Parallel Brain Surgery Simulation with the extended finite element method (XFEM and FleXFEM) (University of Glasgow) -- funding body is EPSRC.
One year MSc in HPC in Edinburgh (all costs covered by funding) + 3 year Ph.D. and access to HecToR, one of the world's largest super-computer, including training with experts in massively parallel simulation (10,000+ processors).
This is a fully funded research project at the University of Waterloo, Canada. The objective is to construct a PECVD and a UV cure chambers for porous dielectric thin film depositions. In addition to building chambers, the candidate will conduct experiments in thin film fracture and small scale deformation. Please email your CV to firstname.lastname@example.org
The Computational Science and Engineering Program at the University of Illinois at Urbana-Champaign is seeking highly qualified candidates for one post-doctoral research associate position in the Center for Simulation of Advanced Rockets.
Hello, I am trying to run a laminted composite plate in ansys. I have all the required mechanical properties and the know how to put some of the information. So far, the many trials I did i can't extract the failure criteria results. I want to know whether the plate fails in normal, shear or compression. I appreciate if someone can give me the map of how to get to that result and at what force. what are the step that i have to take in order to get there.
Im trying to model a rotating uniform beam for 12 rotational speeds in Abaqus using c3d20 elements. As expected, "step 1 to step 5" the frequencies increase as the rotational speed is increased. However, for some strange reason, the frequencies stop varying from the fifth speed. I do get warning messages when running the input file but i cant intepret them well since Im new to Abaqus.
I believe the problem is elementary but i cant figure it out. Can anyone review or run the attached input file to let me know what I am not doing or what exactly is wrong.
People sometimes complain that reading iMechanica takes time. This is because iMechanica has a large number of pages, and new pages are added frequently. If you go directly to iMechanica, you have to load individual pages one by one.
Scaling of fracture strength, fracture energy and toughness is an important issue when it comes to predicting the behaviour of large-scale structures on the basis of laboratory scale measurements. Historically the work of Leonardo da Vinci and Gallileo is well known, followed by the statistical weakest link theory derived by Weibull in 1939. Weibull scaling is a statistical approach assuming instantaneous failure when the weakest link in a material structure fails.
