Task 3 - Multiscale Material Models and Processing Design for Polymeric Materials
Objective: Develop a multiscale internal state variable (ISV) model and specific processing models for polymeric materials that account for statistical variations from the material microstructure, product geometry and processing parameters, and that can aid in the design of polymeric materials for automotive applications. Four main groups of materials will be investigated in this task: 1) Thermoset resins; 2) Nanocomposites and carbon fiber composites; 3) Natural fiber composite products from kenaf bast fiber; 4) Soft biological tissues and animal outer armor.
Approach: We will develop a material database, ISV material models, and process models for different groups of non-metallic materials. The material model will be developed using a multiscale modeling approach, where information from molecular dynamics simulations are to be used to provide insights into the functional form of the ISV's evolution equations and corresponding material parameters.
