Subject aims expressed by acquired skills and competences
Student will gain theoretical and practial knowledge regarding mechanical description and behavior of the plastics, hyperelastic ans composite materials. He will be able to assess effect of the temperature on the mechanical properties of plastic materials, analyse experiments under finite deformations and model hyperelastic and viscoelastic materials by various constitutive models. Student will also gain knowledge about mechanical behavior and simulations of the long fiber composite materials and sandwich beams.

Summary
This topic aims to present a basic introduction to mechanics of non metalic materials. Specificaly, the phenomena which does not exist or are negligible in metalic materials. First part of the lectures is aimed at mechanics of plastics with aim at simulation of glass temperature. Second part of the lectures will aim at introducing the basics of the theory of hyper and visco elasticity together with presentation of some of the common constitutive models used in this area. Last part of lectures will focus on mechanics of long fiber composites.

Other requirements
Active participation on the exercises. Student is excused 2 times. Student must attend to write a test and defend his/her project except for serious health related reasons. This must be proved by the doctor´s written and signed notice. In such cases the test and/or project defense will take place in new date.
If student fails to attendt the test or the project defense he/she will receive 0 points from them.
This subject expects advanced knowledge about strength of materials, laws of elasticity (ability to apply generalized Hook´s law, theory of membranes and thick walled tubes).
