Recent advances of hydrogel network models for studies on mechanical behaviors

Jincheng Lei et al.

Summary: Current constitutive theories face challenges in predicting the extremely large deformation and fracture of hydrogels, calling for the understanding of the fundamental mechanism of various mechanical behaviors from bottom up. Proper hydrogel network models bridge the gap between micro-structure and macroscopic mechanical responses. Different types of network models, including full-atom, realistic, and abstract models, help in explaining the swelling-deswelling process, hyperelasticity, viscoelasticity, and fracture in hydrogels.

A mesoscopic network mechanics method to reproduce the large deformation and fracture process of cross-linked elastomers

Jincheng Lei et al.

Summary: The study introduces a mesoscopic network mechanics method to depict the large deformation and fracture process of the polymer network in cross-linked elastomers. Random network models exhibit lower Young's modulus and less significant strain-hardening stage, indicating that structural randomness is the primary reason for accuracy degradation in existing hyperelastic constitutive models under large deformations.
