From loop probability of self-avoiding walk to constitutive models of hydrogels for thickness, strain-softening and hardening effects

From loop probability of self-avoiding walk to constitutive models of hydrogels for thickness, strain-softening and hardening effects

A novel self-avoiding walk (SAW) chain with loop probability model is proposed, incorporating parameters with clear physical meanings at the microscopic scale. By contrasting it with the phenomenally described Gent model, this research not only discovers the physical foundations of the Gent model...
