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.
Learning Outcomes of the Course Unit
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.
