Finite element structure analysis in an industrial context

OBJECTIVE :

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

COURSE DURATION AND TIMETABLE :

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

GENERAL APPROACH :

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

PREREQUISITE :

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.
