Parameter Identification Methods for Hyperelastic and Hyper-Viscoelastic Models
In this paper, the Ogden model is employed to characterize the hyperelastic properties of rubber, and on the basis of a pattern search algorithm and the Levenberg-Marquardt algorithm, a professional method that can realize the comprehensive fitting of the uniaxial tension, biaxial tension, planar tension, and simple shear experimental data of hyperelastic materials was developed. The experiment...
متن کاملHyperelastic Material Models of Rubber and Rubber-like Materials
ABSTRACT The variety of applications of rubber-like materials in different industrial areas is enormous. In the automotive industry rubber is utilized in tires, as engine and door seals, whereas in aerospace industry rubber rings are used in fuel systems. In other engineering fields, rubbers have been used in conveyor belts, meteorological balloons and vibration isolation bearings or shock and ...
متن کاملTime-multi-scale parameter identification of models describing material fatigue
! Guillaume Puel1 ! 1Laboratoire MSSMat (Ecole Centrale Paris/CNRS UMR8579), Grande voie des vignes, 92290 Châtenay-Malabry, France ! When dealing with the numerical prediction of material fatigue, classical life estimation methods, such as those described in [1], can give poor results as far as one is interested with complex loading histories (such as a loading with a slow-evolving average) ...
متن کاملOn Stress Anlysis for a Hyperelastic Material
Performing a finite element analysis (FEA) on a hyperelastic material is difficult due to nonlinearity, large deformation, and material instability. This paper provides a brief review of the hyperelastic theory and discusses several important issues that should be addressed when using ANSYS. Analysis on a fatigue specimen is used as an example of one of our product development challenges upon w...
متن کاملan experimental and numerical verification of different hyperelastic material models for rubbers under tension and compression loads
some numerical and experimental investigations are made on the performance of five different hyperelastic constitutive models (second order polynomial, yeoh, arruda-boyce, ogden and marlow) in tension and compressionmodes. first, the results of the tensile and compression tests on a rubber sample were used to determine the parameters of the models by curve fitting methods. next, by using an alg...
