The goalThe main objective of this course is to introduce the student to a behavior of composite materials through the theoretical analysis and computational examples. Existence of a course like this one is completely justified, especially if you take into a consideration that implementation of elements of the observed materials in engineering constructions is growing significantly.
The outcomeAfter passing this course students will make their knowledge about composite materials complete. They will be ready to apply it for solving practical problems, different computations, and to design constructions made of composite materials.
