**1. Course Outline & Descriptions**

Continuum Mechanics studies motions of continuum materials. In this course, I will cover fluids, elasticity, and plasticity. It is designed for graduate students to have a global picture of continuum mechanics from the perspectives of classical field theory and differential geometry. I will take three approaches : Newton, Lagrange, and Hamilton, both in Lagrangian and Eulerian coordinate frames of references. Thus, variational principles of fluid mechanics and solid mechanics, Hamiltonian Fluid Mechanics, Hamiltonian Elasticity will be studied.
