A molecular network constitutive model is proposed in this *** on the concept of molecular network decomposition,the molecular network was decomposed into a James-Guth 3-chain network model and an Arruda-Boyce 8-chain network *** that the single molecular chain of rubber is constrained by the surrounding molecular networks, the 3-chain model and the 8-chain model were consequently modified using the tube *** proposed model contains four material parameters that were determined by fitting the uniaxial tensile test data from rubber-like materials,and the values of these parameters were utilized to determine the pure shear and the biaxial *** proposed model agrees well with the experimental data and can predict the test results of experiments performed under the conditions of pure shear and equi-biaxial deformation with acceptable accuracy.

The stress field near the notch tip of an incompressible rubber-like specimen under the condition of plane strain

引用

Science China Mathematics 1995年第10期38卷 1220-1231页

作者：刘波高玉臣 Department of Power Mechanics Hebei University of Technology Tianjin 300132 China

Using Gao’s constitutive relation, the stress fieid has been analyzed near the notch tip and the crack tip of an incompressible rubber-like specimen under the condition of plane strain. The asymptotic equation of the notch tip field is solved numerically; the stress and strain singularities are calculated for various notch angles and different material constant values; the stress variation with the angle coordinate is also analyzed.

Improved Carroll’s hyperelastic model considering compressibility and its finite element implementation

引用

Acta Mechanica Sinica 2021年第5期37卷 785-796,I0002页

In engineering component design,material models are increasingly used in finite element simulations for an expeditious and less costly analysis of the design *** such,researchers strive to formulate models that are less complex,robust,and *** the realm of hyperelastic materials,phenomenological-based Carroll’s model is highly promising due to its simplicity and *** work proposes its further improvement by modifying the strain energy density function to comply with the restriction that it should vanish at reference configuration and adding a compressible term to capture the practical behavior of elastomeric materials and to avoid numerical problems during finite element *** model constants for both the original and the modified versions were obtained by fitting their respective expressions to the classical Treloar’s experimental data using the Levenberg-Marquardt *** modified model was implemented using Abaqus CAE 2016 via a vectorized user material(VUMAT)*** of the model predictions with Treloar’s experimental data demonstrated the superiority of the modified version particularly in the equibiaxial loading ***,the simulated and the experimentally observed behavior agreed to a great accuracy thus making the modified model suitable for simulating the loading response of components fabricated of elastomeric materials.
