Design calculation of structures by the finite element and non-linear method
At the end of the course, learners will have acquired:
- the theoretical principles relating to non-linear analysis
- an understanding of modeling methodologies, associated hypotheses and resolution strategies
- the ability to effectively use finite element software in the nonlinear domain.
The course lasts 3 days (18 hours) and includes:
- 6 hours of theory-based lectures
- 6 hours of practice-based lectures
- 3 hours of practical applications with industrial software
- 3 hours of conferences on industrial applications
The course provides the theoretical basis to be able to decide on and select modeling and resolution strategies.
It is for:
- users of calculation/computation tools
- designers working in CAD-computation integration
- those working in research or computation
It aims to enable users to efficiently use finite element calculation codes in the nonlinear domain.
Course level: Advanced
Participants must have mathematical knowledge (matrix calculation, digital analysis) as well as good knowledge of elasticity, material resistance and linear finite element calculation (course GME 005).
