RA position (MS in Engineering System)

We are looking for suitable candidates for a PhD research work in Computational Mechanics and numerical simulation, to be carried out at the Department of Mechanical Engineering, University of Aveiro, Portugal, in one of the following areas:

- development of new finite elements for metal forming applications;

- numerical simulation of metal forming (sheet and bulk forming);

- tubular hydroforming numerical simulation;

- structural stability and buckling analysis of reinforced aircraft panels;

ICoBT 2011 is a new conference which will be held at Imperial College London from 18-21 September 2011. Contributions are welcomed from scientists, engineers and clinicians working in the fields of orthopaedic surgery, dentistry, biomechanics, biomaterials, cosmetic chemistry, biophysics and biomimetics. Abstract submissions are now open!

I am trying to simulate the long term behaviour of the PBT (polybutyelene terephtalate) thermoplastic.

The mesh and initial stress distribution data (after ejection from the mold) were exported from Moldflow commercial program as Abaqus input (*inp) file. By default, I have already got a fist step of the simulation (linear elastic properties of polymer). What I actually need now is to simulate the long-term performance (for example in the interval of hundreds or thousands hours).  It means that the real time scale is of the utmost importance for the analysis.

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

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 ?
