Course outcomes
The students attending this course are expected to become familiar with vector spaces relevant to continuum mechanics and to perform vector and tensor manipulations. They will be able to describe motion, deformation and forces in a continuum, derive equations of motion and conservation laws and use constitutive models for fluids and solids. With these tools at hand
students will be able to solve simple boundary value problems for fluids and solids. As an application of a challenging problem of continuum mechanics, the final part of the course will be devoted to introduce the basics of turbulence and some related computational method.

Topics
- Reminders on Linear Algebra and Tensor Calculus
- The Continuum hypothesis: from microscopic to macroscopic
