Dear Collegues,
On behalf of the International Scientific Committee, I am pleased to inform you of the 3rd International Conference on IMPACT LOADING OF LIGHTWEIGHT STRUCTURES (ILLS 2011) taking place in Valenciennes, France, June 28th-July 1st, 2011: http://ills2011.org
I would like to persue my PhD specializing in carbon nanotubes appliance with in biomaterials or materials. I have a master degree from KTH (Stockholm) in biomedical materials, started my PhD in Karolinska institute (stockholm) for drug delivery vehicles (Dec 2009- march 2010). Mechanical engineering bachelor from the American university in Cairo; majored in material process and manufacturing & industrial science.
Hi All,
I want to model post-tensioning tendons embedded with concrete structure. Both ends of tendons are anchored. Can anyone inform me what kind of element most suitable to model the tendons and concrete structure in ABAQUS? I tried solid part for both items, yet as the tendon diameter is very small if compared to the concrete dimension, the resulting number of mesh on the concrete structure is very large.
I am working on thermal buckling of annular FGM plates using the DQ method in FORTRAN. The results show that for simply-simply edges, the nonlinear thermal buckling loads are greater than those of eigen buckling loads. But for clamped-clamped edges, as it may be expected, the nonlinear buckling loads are under estimate, i.e. they are lower than eigen buckling loads.Why?
Is it possible that the nonlinear buckling analysis gives us an over estimate load ?

Dear Colleague,
I am very pleased to inform you that the 23rd issue of the WW-EAP Newsletter is now available at:
I now have several openings for Masters and PhDs for the following projects:
1) Biomimetic study of the structure, mechanics and design of fish scales (funding: NSF). Involves atomic force and scanning electron microscopy, mechanics of composites and fracture, small scale and in-situ testing, multiscale modeling.
Usually, the position of points in Mohr's circle is attributed to a sign convetion related to shear stresses. It is shown that points in the circle related to shear stresses generating a clockwise moment are in the upper half of the circle as a consequence of the position of principal directions, not due to a convention. I hope this note could help to explain better the use of Mohr's circle in plane stress states.
