This course provides a selfcontained and consistent overview of the mechanical and thermomechanical properties of materials, based on the theory of rational mechanics and thermomechanics. The presentation of the topics is based on the exact theory of continua and requires from the student the ability to follow tensor formalism. Apart from standard topics this course contains recent developments in the field of materials mechanics, and tries to correct some of the errors and misconceptions in the common textbook literature. The course is appropriate for students of all subjects. Last update: VED107 (20.01.2015)



Students will be able to:
use the most important concepts related to stress and strain tensors, correctly choose and and evaluate mechanical tests, correctly interpret their results, use the correct terminology for the presentation of results and grasp the underlying theoretical principles of materials mechanics to the degree and depth necessary for a full understanding of the modern specialized literature in the field.
