Content summary[edit | edit source]
This course is the micromechanics of composite materials. The purpose is to show you ways in which micromechanics may be used to determine the effective properties of composites.
Goals[edit | edit source]
This learning project aims to
- Show you some of the fundamental theorems in the micromechanics of composites.
- Give you a feel for how the theory can be used to determine the effective properties of composites.
- Give you an idea about numerical approaches based on the theory.

Learning materials and learning projects are located in the main Wikiversity namespace. Simply make a link to the name of the lesson (lessons are independent pages in the main namespace) and start writing!
You should also read about the Wikiversity:Learning model. Lessons should center on learning activities for Wikiversity participants. Learning materials and learning projects can be used by multiple projects - and you are encouraged to cooperate with other departments that use the same learning resource.
