NET v1.0: A framework to simulate permanent damage in elastomers under quasi-static deformations
Abstract
An analytical software for network evolution theory (NET) to describe the macroscopic behavior of filled rubber-like materials at different loading directions is presented. The software is based on a modular platform that is particularly designed to capture Mullins effect, permanent set, and deformation-induced anisotropy. Other inelastic features of elastomers can be modeled and added to the framework. Only the basic framework is covered in the NET v1.0, which is based on the decomposition of the network to two parallel networks of pure rubber (CC) and a polymer-filler (PP). NET v1.0 is developed in Maple©, has 7 material parameters that should be obtained by fitting, and 21 state variables that will be set internally. Experimental data can automatically be imported into NET from an Excel spreadsheet or direct output of a testing machine. To fit the experimental data, the model will be fitted to one full cycle by using the general Levenberg–Marquardt algorithm. The code helps users to fit and optimize the response of an elastomeric component in conceptual and preliminary design before deciding on implementing in the large-scale FE analysis.
