WRITTEN AND ORAL TEST

A good knowledge of the basic concepts given within the courses of Mechanics of Solids and Structures, Numerical Analysis, and Computational Mechanics is required.

This course aims at giving a concise introduction to the basic concepts of nonlinear mechanics of solids and at providing the basic ingredients to perform simulations of solid mechanics problems at large strains via the finite element method.

• Basics of nonlinear mechanics:
Kinematics
Equilibrium
Hyperelastic constitutive laws

• Elements of numerical analysis:
Solution of nonlinear equations and systems: theory and Matlab implementation of basic algorithms
Nonlinear finite elements

• Application to 1D rods at large strains (and Matlab implementation)

• Application to 2D plane strain problems at large strains (and Matlab implementation)

• Use of a commercial nonlinear finite element code

Blackboard lectures, hands-on tutorials in Matlab, Mathematica, AceGen/AceFEM, and commercial finite element software.
