Course objectives:
|
To explain to students the geometric and dynamic structure of material; how does this structure bear upon the response of the material to mechanical, thermal, (electro)chemical and radiation effects of its environment; and how may the structure of the material and subsequently its properties by improved or, on the contrary, deteriorated.
|
Requirements on student
|
Class ticket: - compulsory attendance at tutorials; - successful passing the check tests. Examination: successfully pass both written and oral examination.
