Non-linear Buckling in Ansys

Choose a channel featured in the header of iMechanica: 

Hello to all,

                 I m mahendra and i want few suggesions for my final year project Regarding Non-Linear buckling of composite Wind Turbine. I have done Linear Buckling and got a BLF=1.3 which is fine as per GL Guidlines. I m using Ansys12 Edu ver. and Shell 281 Element type with section properties. For load application i m using pilot node at 9 airfoils on the full blade.

Then i have applies Mx and My on that load application points.

In Non-Linear Analysis i m not getting the convergence as i m applying load on one node or at all the 9 points.

Deadline is approaction: 10 april - "Risø Int. Symposium: Composite materials for structural performance: towards higher limits"

The deadline for abstract submission for the 32, 10th April 2011, is approaching. The title of the 32nd Risø International Symposium on Materials Science is "Composite materials for structural performance: towards higher limits". The Symposium will be held from Monday 5th September to Friday 9th September 2011 at Risoe DTU - National Laboratory for Sustainable Energy, Technical University of Denmark, 4000 Roskilde, Denmark. We think this is an exciting Symposium theme and we are proud to present a great list of key-note presentations:
