Creep and Relaxation of Nonlinear Viscoelastic Materials William N. Findley, Kasif Onaran, Frances A. Davis
Publisher: Dover Publications

The viscoelastic relaxation modulus obtained for the same material from the linear viscoelastic measurements was used to describe the behavior in the nonlinear regime for validating the class of the additive constitutive models. In addition, many materials of engineering importance exhibit significant nonlinear viscoelastic behavior in physical environments and under mechanical loading of practical interest, especially under high-temperature conditions. Section 3 deals with the problems associated with the determination of the Constitutive Equation of nonlinear viscoelastic materials. Mechanics of Composite Materials (Dover Civil and Mechanical Engineering) Viscoelastic Materials. I find that much more work is published on the nonlinear elasticity aspects of soft materials and potentially important time effects get missed; especially in impact loading the time element is a critical consideration. Analytical Fracture Mechanics (Dover Civil and Mechanical. Creep and Relaxation of Nonlinear Viscoelastic Materials (Dover Civil and Mechanical Engineering) [William N. Yes i understand that Abaqus uses the creep data and converts it to relaxation data, through convolution integrals i think. Springs represent the Densification region is controlled by last spring with nonlinear stiffness kD . The limitations of the additive model were clearly revealed. With spherical indenters the use of linearly viscoelastic models for characterization of a material creep or relaxation function is straightforward. Dover Civil and Mechanical Engineering Theory of viscoelasticity - Richard M. These models have been used to modeling the behavior of a viscoelastic materials (creep and stress relaxation). R m christensen - AbeBooks - AbeBooks Official Site - New & Used. Elements for the Numerical Analysis of Wave Motion in Finally a method is presented for the comparison and evaluation of the consistency of creep and relaxation data obtained by a set of independent experiments. For analysis of experimental data has progressed substantially. When you say the data is not covering a wide enough range to accurately Also, polypropylene is a non-linear viscoelastic material (as are most polymers), and modelling viscoelasticity in Abaqus in the way outlined above only encompasses a linear viscoelastic response.
