Finite Element Methods and Practical Stress Analysis

Venue
The Aeronautical Society of India (AeSI)
Bangalore

Febuary 8-9 2008

Overall, this programme is designed to enhance the functional knowledge of new FEM users in the aspects of practical stress analysis.

The salient aspects of this workshop are –

• The tutorials would be handled by very experienced industry exposed users of FEM.
• This course would offer vital guidance to judge which approximations are acceptable for solving the practical problems.
• The methods of verifying and validating the FEM results would be demonstrated with real world case studies.
• Each participant would be provided with high quality training notes.

Who Should Attend?

The contents of this programme are specially designed keeping the needs of junior and middle level analysts who have to apply FEM for solving practical stress analysis problems.

The material that is presented is independent of any particular software package, making it ideally suited to current and potential users of all commercial finite element software systems. The workshop is open to both members and non-members of NAFEMS.
