Finite Element Methods and Practical Stress Analysis

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

The salient aspects of this workshop were –

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