This article focuses on physically cross-linked hydrogels with dynamic reversible cross-linking and attempts to understand their constitutive behavior characteristics. By studying classical hyperelastic and viscoelastic models, the advantages and limitations of these models in describing the deformation behavior of physically cross-linked hydrogels are analyzed. Combining with the microstructural characteristics of hydrogels, a new constitutive model is established to describe the rate-dependent behavior of hydrogels, in order to clarify the key factors affecting the rate-dependent stress response of physically cross-linked hydrogels. The aim of this article is to clarify the mechanical mechanism of the complex deformation response of physically cross-linked hydrogels and to provide a foundation for the development of more accurate and comprehensive constitutive models for physically cross-linked hydrogels
