Topological and Mechanical Characterization of Metamaterials

Objectives
This chapter provides a comprehensive knolwledge of the latest advancements in topological modelling of metamaterials as well as in numerical, theoretical and experimental approaches for investigating their mechanical properties. At the end of the course, the student will be able to efficiently represent the 3D geometry of the mematerials, to evaluate the expected geometry and mechanical behavior and to set-up the most suitable experimental tests to validate the mechanical predictions.

Topics
Taxonomy of cellular metamaterials based on geometrical aspects
Main representation schemes adopted in CAD tools: boundary representation and function representation approaches
Modelling approaches and numerical techniques used to predict mechanical properties of additively manufactured metamaterials
Experimental approaches for investigating the static and cyclic mechanical properties of metamaterials
Source of geometrical inaccuracy and metrological methods for geometrical reconstruction

Required Skills
Basics of CAD modeling, basics of mechanics of materials

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 and SW/HW emulator exercises.
The exam consists of a written test with multiple-choice questions on the topics of the course.
