Randomized trial demonstrates non-linearizable elasticity in isotropic materials, suggesting broader applicability in engineering contexts.
Key Points
This research aims to develop a hyperelastic isotropic material model that can predict arbitrary Poisson's ratios and behave nonlinearly under deformation.
Proposed a hyperelastic isotropic model with a positive-definite strain energy function
Analyzed model behavior under various strain states and deformation ranges
Ensured compliance with thermodynamic laws regarding Poisson's ratios
The proposed model can predict Poisson’s ratios greater than 0.5, expanding the typical range of values
Demonstrated that the model is plausible across various strain states
Confirmed the stability of the model under a wide range of deformations
