Course description

The course aims at integrating the basic skills of students with advanced methods for the analysis of structures relying upon nonlinear models and finite-element based computational tools.

Prerequisites

Contents of the course of Continuum and structural Mechanics. Basic knowledge of Matlab programming.

Syllabus
