Course Objectives
At the end of the course, the students will be familiar with the advanced modelling concepts in micromechanical modelling of metallic materials which is necessary for the engineers of the current century. With ongoing miniaturization in several industries new physics based modeling techniques are required to analyze the components having micron dimensions . The classical continuum scale constitutive equations are not valid in this situation. Therefore the students will get informed about the limits of the softwares that they use in engineering analysis and they will learn solutions to overcome these difficulties.
Course Content
Physically based constitutive modeling of solid materials. Overview of the phenomenological type of plasticity models. Crystal plasticity modelling of single crystal materials. Non-local (gradient) material modelling approaches. Strain gradient crystal plasticity of single crystal materials. Modelling of polycrystalline metals. Non-convexity and localization phenomena. Phase field modelling approaches.
Course Learning Outcomes
The achievement of the learning objectives will be measured through the students' ability to apply fundamental mathematical tools to solve micromechanical problems, which will include constitutive relation derivation using tensors, finite element implementation of the simplified versions and numerical analysis using commercial softwares.
