GME-018
Structures: calculations, design, tests, certification - 2019

Design calculation of structures by the finite element and non-linear method

OBJECTIVE :

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.

COURSE DURATION AND TIMETABLE :

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

GENERAL APPROACH :

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.

PREREQUISITE :

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).
