商品描述

This book examines the electro- and magneto-mechanics of soft composite materials and structures, and focuses on magnetorheological elastomers (MREs) and dielectric elastomer composites (DECs), which are composite materials that comprise ferromagnetic and high-dielectric/conducting filler nano- and micro-particles embedded in a soft polymeric matrix. This gives rise to a coupled magneto- and electro-mechanical response at the macroscopic (order of millimeters and larger) scale when they are subjected to magneto- electro-mechanical external stimuli. While such MRE and DEC materials and devices can become unstable at some critical electro-magneto-mechanical loading, their response may be well controlled in the post-instability regime. Moreover, recent advances on the complete electro-magneto-mechanical coupling are presented. All those aforementioned features motivate the operation of these devices in this unstable region to obtain controlled pattern formation, soft robotic motion andartificial muscles, controllable band-gap acoustic and electromagnetic properties, energy harvesting as well as actively controlled stiffness (for cell-growth). The book contains four individual chapters covering work on the fundamentals (O. Lopez-Pamies) and the modeling (M. Gei) of electroactive solids, the modeling of magnetoactive solids (K. Danas), and the analysis of elastic instabilities (Y. Fu).

商品描述(中文翻譯)

本書探討了軟性複合材料和結構的電磁力學和磁力學特性,並專注於磁流變彈性體(MREs)和介電彈性複合材料(DECs)。這些複合材料由鐵磁性和高介電/導電填充劑的納米和微米粒子嵌入在軟性聚合物基質中組成。當它們受到磁電力學外部刺激時,在宏觀尺度(毫米及以上)上產生耦合的磁電力學反應。儘管這些MRE和DEC材料和裝置在某些臨界磁電力學負載下可能變得不穩定,但它們的反應在後不穩定區域可以得到良好控制。此外,本書還介紹了關於完整的磁電力學耦合的最新進展。所有上述特點激發了在這個不穩定區域內操作這些裝置,以獲得受控的圖案形成、柔性機器人運動和人工肌肉、可控的帶隙聲學和電磁特性、能量收集以及主動控制的硬度(用於細胞生長)。本書包含四個獨立的章節,分別介紹了對電活性固體的基礎研究(O. Lopez-Pamies)和建模(M. Gei),對磁活性固體的建模(K. Danas)以及彈性不穩定性的分析(Y. Fu)。

作者簡介

Kostas Danas holds a tenured position as a CNRS Director of Research (Directeur de Recherche) and Professor at the Solid Mechanics Laboratory (LMS), Department of Mechanics at Ecole Polytechnique, where he teaches courses on continuum and fracture mechanics. His research focuses on the numerical, theoretical and experimental analysis of microstructured active elastomers and their instabilities as well as on the modelling and fracture of metallic and 3D printed polymeric porous materials.

Oscar Lopez-Pamies holds PhD degrees in Mechanical Engineering and Applied Mechanics from the University of Pennsylvania (USA) and the École Polytechnique (France). He is currently the Colonel Harry F. & Frankie M. Lovell Endowed Professor at the University of Illinois Urbana-Champaign, where he teaches graduate and undergraduate courses on the mechanics of solids, constitutive modeling, homogenization, and numerical methods for PDEs. His research focuseson the development of mathematical theories and associated numerical methods to describe, explain, and predict the mechanical and physical behavior, stability, and failure of solids.
