Learning objectives
- Students have to understand the basics of equilibrium of forces and moments.
- They need to have operational knowledge of vector- and tensor calculus in coordinate free notation as well as matrix notation after introduction of a basis.
- Solve the one-dimensional equilibrium equation and have basic knowledge on 2- and 3-dimensional equilibrium equations.
- A good understanding of the definitions and properties of the stress and strain tensors. Interpret and use them.
- Understand the deformation rate tensor, the spin tensor and the velocity gradient tensor
- Determine gradients in scalar and velocity fields
- Describe movement of particles through a field
- Understand constitutive behaviour of isotropic solids for small and large deformations and Newtonian fluids.
