Hyperelastic behavior
Web14 apr. 2024 · For supporting this observation, we demonstrate an extreme case of 10% infill ratio that this hyperelastic behavior remains as a system response. By excluding less than 50% infill ratio – Fig. 1 indicates a rule-of-thumb that the microstructure turn into the same length-scale as the bulk – we may compare 70% and 50% and understand that the load … Web2 jun. 2024 · Here, we identify a hyper-viscoelastic damage model that we fit to original data on the nonlinear, viscoelastic behavior of blood clots. Our model combines the classic Ogden hyperelastic constitutive law, a finite viscoelastic model for large deformations, and a non-local, gradient-enhanced damage formulation.

WebAn adhesive film exhibits hyperelastic and viscoelastic behaviors; therefore, the constitutive model of an adhesive film must consider both these types of behavior simultaneously. Numerous hyperelastic models exist, such as the Mooney–Rivlin model [ 3 , 4 ], Ogden model [ 5 ], Yeoh model [ 6 ] and Arruda–Boyce model [ 7 ]. Web26 nov. 2024 · Hyperelastic materials will exhibit elastic deformations excessively before failure without irreversible deformation. These materials exhibit an extremely nonlinear stress-strain behavior that ascends monotonically up to fracture.
