	Teaching Methods
	THE COURSE CONSIDERS THEORETICAL LECTURES AND NUMERICAL APPLICATIONS DEVELOPED IN THE CLASSROOM, INTEGRATED BY SOME LABORATORY TESTS. ATTENDANCE AT THE LECTURES IS STRONGLY RECOMMENDED.

	Verification of learning
	TO HAVE REACHED THE PREFIXED AIMS IS EVALUATED BY WRITTEN AND ORAL EXAMINATION. WRITTEN EXAMINATION. CRITERIUM FOR MINIMUM THRESHOLD THE STUDENT HAS TO PROVE THAT HE KNOWS HOW TO SOLVE FOR DETERMINING BOUNDARY CONSTRAINTS AND STRESS RESULTANT DIAGRAMS. CRITERIUM FOR EXCELLENCE. THE STUDENT SHOWS A SURE DIMENSIONING OF A SIMPLE STRUCTURE HIGHLIGTHING GOOD KNOWLEDGE OF THE EMPLOYED FORMULAS. ORAL EXAMINATION. CRITERIUM FOR MINIMUM THRESHOLD THE STUDENT HAS TO PROVE THE GOOD KNOWLEDGE OF THE FORMULATIONS CONNECTED TO THE STRESS RESULTANTS, REPRESENTING THEM FOR PLANAR BEAM STRUCTURES, KNOWING THE APPLICATION OF A STRNGTH CRITERIUM TO A GENERAL STRESS TENSOR, KNOWING HOOKE'S LAW. CRITERIUM OF EXELLENCE IN ADDITION TO THE ABOVE, THE STUDENT HAS TO SHOW THE THEORETICAL DEVELOPMENT OF THE FORMULAS RELATED TO THE STRESS RESULTANTS, DETERMINING PRINCIPAL STRESSES AND MAXIMUM TANGENTIAL STRESSSES, USING DIFFERNT STRENTH CITERIA, EVALUATING MEMBRANAL STRESSES FOR VESSELS, DEVELOPING FATIGUE CALCULATIONS. THE WRITTEN EXAMINATION ONCE PASSED WILL BE CONSIDERED VALID FOR THE ENTIRE EXAMINATION SESSION (SUMMER, AUTUMN AND EXTRAORDINARY) IN WHICH IT WAS TAKEN. IF THE STUDENT DOES NOT ATTEND THE ORAL EXAMINATION IN THE RELEVANT EXAMINATION SESSION, THE WRITTEN EXAMINATION WILL NO LONGER BE CONSIDERED VALID AND THE STUDENT WILL HAVE TO TAKE ANOTHER ONE. ONCE PASSED, THE WRITTEN EXAMINATION WILL BE THE SUBJECT OF AN INTERVIEW DURING THE ORAL EXAMINATION. DURING THE COURSE IT CAN BE TAKEN TWO PARTIAL WRITTEN TESTS, RESPECTIVELY AFTER HALF OF COURSE AND AT THE END OF THE SEMESTER. EACH TEST WILL WEIGH 50% OF THE TOTAL GRADE. IF THE GRADE WILL BE HIGHER THAN 18/30 THE STUDENT MAY CONSIDER HIMSELF EXEMPT FROM THE WRITTEN TEST. THE EXEMPTION WILL ONLY APPLY TO THE EXAMINATION SESSION FOLLOWING THE TEACHING SESSION. THE FINAL GRADE, EXPRESSED IN THIRTIETHS WITH POSSIBLE PRAISE, WILL DEPEND ON THE OVERALL MATURITY ACQUIRED ON THE CONTENTS OF THE COURSE.
