Kinetic modeling of viscoelastic materials - A parallel approach
Abstract: Viscoelastic materials are characterized by the coupling of microstructural changes to macroscale deformations. In this talk, we discuss an elastic dumbbell model that leverages the parallel processing power of High Performance Computing (HPC) Graphics Processing Units (GPUs) to create a unique micro-macro scale driven design which incorporates the nonlinear nature of viscoelastic responses as well as the stochastic processes which describe the breaking and reforming of entanglements in the underlying microscopic network. The model allows a full reconstruction of the microstructure-flow coupling thereby creating a platform with the ability to investigate how microscopic changes affect macroscopic responses. Here, we focus on oscillatory flow and show both evolution of stress and species distribution as functions of frequency and strain.
