	Teaching Methods
	THE COURSE IS OF 12 CFU AND COVERS THEORETICAL LESSONS, WHICH WILL BE PRESENTED DURING THE COURSE TOPICS THROUGH LECTURES AND CLASSROOM EXERCISES, DURING WHICH PROVIDE THE MAIN TOOLS NEEDED FOR SOLVING EXERCISES RELATED TO THE CONTENT OF THE THEORETICAL ASPECTS. IS AN OBLIGATION AT LEAST 70% FREQUENCY OF HOURS OT TEACHING EXPERIENCE

	Verification of learning
	THE EXAM IS AIMED AT EVALUATING THE KNOWLEDGE AND THE ABILITY TO UNDERSTAND THE CONCEPTS EXPOSED DURING LESSONS AND THE ABILITY TO APPLY SUCH KNOWLEDGE AND TO FORMULATE THE DIFFERENTIAL EQUATIONS DESCRIBING THE DYNAMIC OF MATERIAL SYSTEMS. THE EXAMINATION IS CARRIED OUT AT THE END OF THE COURSE AND IS DIVIDED INTO A SELECTIVE WRITTEN TEST AND IN AN ORAL INTERVIEW. THE WRITTEN TEST IS CARRIED OUT IN 3 HOURS AND PROPOSES EXERCISES AND QUESTIONS WITH OPEN ANSWERS. THE ORAL INTERVIEW EVALUATES THE ACQUIRED KNOWLEDGE. IN THE FINAL EVALUATION, EXPRESSED IN THIRTIETHS, THE ASSESSMENT OF WRITTEN TEST WEIGHS FOR 40%, WHILE THE ORAL INTERVIEW WEIGHS FOR THE REMAINING 60%. TO ACHIEVE THE LEVEL OF EXCELLENCE IT WILL BE CONSIDERED: 1.THE USE OF APPROPRIATE SCIENTIFIC LANGUAGE; 2. THE TRANSVERSE CORRELATION BETWEEN THE DIFFERENT ARGUMENTS OF THE COURSE AND WITH OTHER DISCIPLINES; 3. THE AUTONOMY OF JUDGMENT.
