The goalA major goal of this course is to enable students to understand mechanical behavior of laminar composite plates and shells through professors theoretical analysis and computational examples. The existence of this course is completely justified if you take into a consideration the fact that implementation of the elements of certain geometry in engineering constructions has the growing significance. Analysis of micro and macro-mechanical behavior of composite materials will be taught in this course. After lectures of introduction about basic parameters of elasticity and strength of these materials, special attention is ascribe to the analysis of a different tensions and layer deformations, that can occur in plates and shells of composite materials. Beside these properties, strentgh and criteria of damage and crack are also observed.
The outcomeAccomplishing the objectives of the course will enable students to complement their knowledge on composite materials and they will be ready to apply it on real examples, computation and design of composite material construction in a shape of lamina and shells.
