| Abstract | We consider generalized one-dimensional Maxwell and Kelvin-Voigt models of viscoelastic materials in which the properties of elastic and viscous elements are determined by the corresponding secant moduli and viscosity coefficients, which are functions of the parameters determined by the deformation process. In contrast to the nonlinear endochronic theory of aging viscoelastic materials (NETAVEM), in which one and the same aging function is used to describe the properties of all elastic elements and one and the same viscosity function is used to describe the properties of all viscous elements [1, 2], it is assumed that the type of these functions is distinct for each elementary model. For the generalized Maxwell and Kelvin-Voigt models under study, we obtain representations of the specific work of internal forces as the sum of four terms of different physical meaning. There representations are similar to those given in [1, 2] for NETAVEM. An example of construction of viscoelasticity constitutive relations containing two aging functions and one viscosity function is given for a material whose properties are sensitive to the strain rate. The simultaneous use of several aging and viscosity functions to describe the properties of structure elements of the model and the use of several components of specific work as arguments of these functions allows us to extend the scope of the models under study. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
