Analysis and Design of Linear and Nonlinear Metastructures

Objectives
This course offers a comprehensive introduction to nonlinear structural dynamics including significant nonlinear oscillators and relevant methods of solutions. It is based on a balance between theory and applications, and includes the latest advances in metastructure research. Nonlinearities, hysteretic oscillators, quasi-periodic structures and metastructures will be discussed for the vibration mitigation of industrial components and small modular reactors. Theoretical classes will be complemented by numerical exercises and lab experiments.

Topics
Introduction to finite lattices and metastructures
Motion in large. Perturbation methods. Duffing oscillators
Solutions of the dynamics of a nonlinear cell
Analysis of quasi-periodical and periodic metastructures
Vibration mitigation of industrial components and small modular reactors
Hands-on tutorials and lab experiments

Required Skills
Courses of “Foundations of Mechanics and Acoustics”

Course Modality and Verification of Learning
The classes will be given in hybrid (i.e., onsite and online) format. The teaching activity includes theoretical lessons, exercises and lab experiments.
The exam consists of a written test with multiple-choice questions on the course topics.
