Teaching Methodologies and Assessment Criteria |
Weekly: 2 hours of lectures. The teacher presents and explains the subjects with a didactic character; 2 hours of classes with resolution of exercises and analysis of case studies (scientific articles) using worksheets with questions such as analysis methodology. PROJECT WORK (Proj) Development of work (report) in groups of 2 or 3 students with tutorial support and presentation to the class. LABORATORY WORK (TLab) Demonstration class: 1) manufacturing processes of composites laminates (thermosetting and reinforcing tissue and pre-impregnated in autoclave); 2) composite damage analysis in tensile, flexural and low speed impact tests. EVALUATION TEST (TA) Individual knowledge test. FINAL EVALUATION FINAL GRADE = [0.6 x TA] + [0.3 x Proj] + [0.1 x TLab] Minimum grade for access to the Exam: 5 points. The continuous evaluation (Project and laboratory) is considered in the Exam. The final exam grade is obtained by the equation: EXAM GRADE = [0.6 x EXAM] + [0.3 x Proj] + [0.1 x TLab]
