Knowledge of calculus, basic concepts of continuum mechanics, solid mechanics.

This course is an introduction to the finite elements method: basic structural schemes are developed and solved using commercial software. In the second part Certification issues are analysed. The course is closed by an experience in Laboratory where a static test is designed, carried out and analysed.

Capability of developing a finite element model for structural applications
Capability of interpretation of the numerical results

Capability of debugging numerical models
Knowledge of the certification process in the aeronautical field
Knowledge of how a structural certification test is carried out
