Article Tittle: Advances in Research on Thermo-Electro-Chemo-Mechanical Coupling Problem for Intelligent Soft Materials

Author: Yang Qingsheng, Wei Wei, Ma Lianhua

Abstract:

This paper presents an overview of research on multi-field coupled mechanics for typical intelligent soft materials, including polymer gels, hydrogels biological soft tissures and so on. Attention is paid to the foundamental theory and research methods of thermo-electro-chemo- mechanical coupling behavior for such materials. The typical progresses on this issue in research groups over the world are reviewed. Based on phenomenological thermodynamics theory and Hamilton principle, a general theory framework on thermo-electro-chemo-mechanical coupling problem is established. Focusing on chemo-mechanical constitutive laws and governing equations, from Hamilton principle and its closeness is proved. The finite element formulation and one-dimensional analytical solution of the chemo-mechanical obtained. Several numerical examples are used to illustrate the multi-field coupled behavior of hydrogels and articular cartilages. Finally, the research topics and trends in future on the multi-field coupling for intelligent soft materials are discussed.

Keywords: intelligent soft materials, thermo-electro-chemo-mechanical coupling, chemo-mechanical coupling, constitutive equations, Hamilton's principle, finite element method
