Finite element structure analysis in an industrial context
Through this training, the trainees should be able of:
- Increase their level of knowledge of FE static analysis and FE modal dynamic analysis
- Acquire basic knowledge related to Non-Linear FE and transient dynamic FE (crash and impact analysis)
- Better knowledge related to modelling methodologies, modelling assumptions and the confidence in the analysis results
This training duration is 5 days (30 hours) including:
- 3 h conferences on present challenges of FE analysis
- 3 h practical applications on commercial FE code
- 2 h FE code demonstration
- 3 h modelling practice
- 5 h conferences on industrial applications
This training supports methods’ acquisition allowing trainees to deal with modelling options then select the most appropriate ones in term of FE model robustness. Target application and sizing objective / context are part of the training objectives.
This training is targeting:
- FE code day-to-day users
- designers dealing with CAD to CAE integration
- supervisors of structure analysis teams or work packages
It provides background to FE code users regarding:
- key role of modelling assumptions
- limitations of analysis tools
Level: Improvement
Participants should have mathematical background (matrix calculation, general numerical analysis) learned in universities and engineering schools. Also good knowledge in material strength analysis is required.
