AEE563 CONSTITUTIVE MODELING OF ENGINEERING MATERIALS

Course Objectives

The objective of the course is to introduce the fundamentals of constitutive modeling of deformable solid materials to students and to familiarize them with various kinds of elastic and inelastic material responses. To this end, the course covers elastic, viscoelastic, plastic, viscoplastic material responses, and continuum damage mechanics and discusses how microstructural mechanisms influence the macroscopic mechanical behavior in different materials. The course also aims at equipping students with the necessary background to develop constitutive models that can be used in commercial/research finite element software for the analysis of complex aerospace structures and components. The course is restricted to small strain (geometrically linear) kinematics.

Course Content

Constitutive modeling of solid materials. Rheological models. Classification of different kinds of material response. Isotropic and anisotropic elasticity. Viscoelasticity. Plasticity and viscoplasticity of metals. Phenomenological plasticity and viscoplasticity models. Introduction to continuum damage mechanisms.

Course Learning Outcomes

At the end of the course, students are expected to learn:

• the fundamentals of constitutive modeling of deformable solid materials,

• how microstructural mechanisms influence the macroscopic mechanical response in different materials,

• various kinds of elastic and inelastic, e.g., plastic, viscoplastic, viscoelastic, material responses,

• fundamentals of viscoelasticity, rate-independent plasticity, rate-dependent plasticity (viscoplasticity), and damage mechanics,

• how to develop constitutive models that can be used in commercial/research finite element software for the analysis of complex aerospace structures and components.
