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 four individual works in class and prepare four laboratory works in group.
Fórmula de cálculo da classificação final
NF = 50%*AT + 50%*TL
AT (presentation of four 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.
