摘要

形状记忆聚合物(SMPs)和形状记忆复合材料(smpc)具有良好的自致动、变形和自适应性能，已广泛应用于多个领域。建立合理的本构模型对于理解形状记忆机理和扩大形状记忆的应用具有重要意义。此外，还可以预测smp在不同条件下的力学响应，便于对其进行精确控制。在大多数smp中，形状记忆行为的内部机制是热致动。本文综述了热驱动SMPs的理论、流变和相变概念模型，以及流变和相变概念相结合的模型。总结了颗粒增强、碳纤维增强复合材料的本构模型以及复合材料的屈曲行为。本研究将有助于快速解决剩余问题，并有助于建立合理的smp和smpc本构模型。

Thermomechanical Constitutive Models of Shape Memory Polymers and Their Composites

Shape memory polymers (SMPs) and SMP composites (SMPCs) have been widely employed in several fields and exhibit excellent self-actuation, deformation, and self-adaption. Establishing reasonable constitutive models is vital for understanding the shape memory mechanism and expanding its applications. Moreover, the mechanical response of SMPs under different conditions can be predicted, facilitating their precise control. The internal mechanism for the shape memory behavior in most SMPs is thermal actuation. This study reviews the theories of thermally actuated SMPs, rheological and phase transition concept models, and models combining the rheology and phase transition concept. Furthermore, the constitutive models of particulate-reinforced SMPCs, carbon-fiber-reinforced SMPCs, and the buckling behavior of SMPCs are summarized. This study is expected to help solve the remaining issues rapidly and contribute to the establishment of rational constitutive models for SMPs and SMPCs.

期刊介绍： Applied Mechanics Reviews (AMR) is an international review journal that serves as a premier venue for dissemination of material across all subdisciplines of applied mechanics and engineering science, including fluid and solid mechanics, heat transfer, dynamics and vibration, and applications.AMR provides an archival repository for state-of-the-art and retrospective survey articles and reviews of research areas and curricular developments. The journal invites commentary on research and education policy in different countries. The journal also invites original tutorial and educational material in applied mechanics targeting non-specialist audiences, including undergraduate and K-12 students.
