Adaptive Materials for Structural Applications
Last Updated: 2026-02-05 16:16:29
Abstract
Adaptive materials offer appealing ways to extend the design space of structures by introducing time-variable properties into them. In this course, the physical working principles of selected adaptive materials are analyzed and simple models for describing their behavior are presented. Some applications are illustrated, also with laboratory experiments where possible.
Objective
The study of adaptive materials covers topics that range from chemistry to theoretical mechanics. The aim of this course is to convey knowledge about adaptive materials, their properties and the physical mechanisms that govern their function, so as to develop the skills to deal with this interdisciplinary subject.
Content
This course will provide the students with an insight into the properties and physical phenomena which lead to the features of adaptive materials. Starting from chemomechanical (skeletal muscles), the physical behavior of a wide range of adaptive materials, thermo- and photo-mechanical, electro-mechanical, magneto-mechanical and meta-materials will be thoroughly discussed and analyzed. Up-to-date results on their performance and their implementation in mechanical structures will be detailed and studied in laboratory sessions. Analytical tools and energy based considerations will provide the students with effective instruments for understanding adaptive materials and assess their performance when integrated in structures or when arranged in particular fashions. Basic concepts: Power conjugated variables, dissipative effects, geometry- and materials-based energy conversion Chemo-mechanical coupling: Energy conversion in skeletal muscle and other chemomechanical systems,optional: and photo-mechanical coupling, azopolymers. Thermo-mechanical coupling: Shape memory alloys / polymers Electromechanical coupling(1): DEA, EBL, electrorheological fluids Shape control / morphing: Use, requirements, challenges Morphing applications of variable stiffness structures: Lab work Electromechanical coupling (2): Piezoelectric, electrostrictive effect Vibration Reduction: Measurement, passive, semi-active (active) damping methods Vibration reduction applications of piezoelectric materials: Lab work Metamaterials: Definition of metamaterials - electromagnetic, acoustical and other metamaterials Energy harvesting and sensing: Energy harvesting with EAP and piezoelectric materials, transducers as sensors: Piezo, resistive,...
