Objetivos
Understand and know how to analyze the various modes of degradation of materials, namely fracture, fatigue, creep, wear and corrosion.
Resultados de aprendizagem e competências
Identify and justify structural failure modes. Use fracture, fatigue, creep, wear and corrosion behavior models for the design of structures.
Modo de trabalho
B-learning
Programa
Introduction: Presentation of several cases studies of degradation modes of ruin. Friction: Friction Laws, Friction Models, Relationship between friction and operational conditions. Wear: adhesive wear, abrasive wear, fatigue wear and tribochemical wear. Corrosion: Corrosion categories. Corrosion Protection. Fracture: Introduction and concepts, Brittle and Ductile fracture, Facture conditions, Linear Elastic Fracture Mechanics. Fatigue: Definition and characterization of the fatigue process, Fatigue S-N curves and their fundamental parameters, Oligocycle fatigue, Application of linear elastic fracture mechanics in fatigue crack propagation. Creep: Introduction and basic definitions.

Obtenção de frequência
The student must present three individual works in class, prepare four laboratory works in groups and answer three questionnaires during classes.
Fórmula de cálculo da classificação final
NF = 50%*AT + 40%*TL + 10 % Tests
AT (presentation of three papers in class)
TL (elaboration of four laboratory assignments)
Provas e trabalhos especiais
In regular or appeal periods, it is possible to replace the grade of the individual assignments with a written exam, with the same weight in the final average.
