报告摘要:

With development of soft machines, the mechanics of soft materials becomes an emerging field in applied mechanics. In last decade, computational methods have become main approaches to study mechanics of soft materials (hydrogels, shape memory polymers (SMPs), elastomers etc.). Simultaneously, different numerical simulation methods (FEM method, molecular dynamics etc.) have been proposed to predict deformation behavior of soft materials. In order to predict the deformation behaviors of soft materials correctly, it is critical to develop proper constitutive models. Since the constitutive models of soft materials are still in under development. Therefore, it is very imperative to assess and discuss the advances of new constitutive models for soft materials.

In this talk, Prof. Liu (speaker) will review some of the recent works aligned with the direction of providing a better understanding of new development of constitutive models of soft materials (such as, hydrogels, SMPs etc.). Since last decade, we have proposed different constitutive models for neutral and environmentally sensitive (temperature, pH-value, magnetics and light) hydrogels. For the SMPs study, we have established series new constitutive models for SMPs. To validate the proposed models, simulated and predicted results are compared with experimental results. As many issues related to the deformation behaviors of hydrogel and SMPs still remain open, we will provide some outlines for plausible future directions in the research of constitutive models in soft materials. Finally, we will overview the recent development of computational mechanics in the study of soft materials; especially, the advances of constitutive models for soft material in different research groups over the worldwide will be discussed and reviewed.
