Arruda–Boyce model

The Arruda-Boyce model is a mathematical framework used to describe the mechanical behavior of rubber-like materials, particularly when they are subjected to large deformations. It is a type of hyperelastic material model that captures the nonlinear elasticity of elastomers and similar materials. The model is based on the idea of a chain of segments that represent the polymeric structure of rubber. It incorporates the effects of molecular chains stretching and the entropic changes associated with these deformations.
