MECH 340 Syllabus, Fall 2011

Engineering Material MECH340 Syllabus Fall 2011 INSTRUCTOR Dr. Salem Seifeddine, Mech.Eng. Room 111, phone ext. 3479 Email: Salem.Seifeddine@aub.edu.lb TEXTBOOK Materials Science and Engineering: An Introduction, by W.D. Callister, 8th Ed., Wiley. GOALS The course introduces fundamental concepts in materials science as applied to engineering materials. It also introduces to sophomore students how the structure of metals, ceramics, polymers, and composite materials and their engineering properties, specifically mechanical properties, are related. The effect of the processing route on the structure and therefore properties of materials is also discussed. The course seeks to impart an understanding of the fundamental nature of materials both metallic and non-metallic. It also introduces the sophomore engineering students to the mechanical, thermal, electrical properties of materials. Furthermore, some key applications of those materials are treated as well as common manufacturing processes used in the fabrication of products. CONTENTS Atomic structure, atomic bonding, the structure of solids; mechanical properties (strength, toughness, hardness, creep and fatigue); Deformation and dislocation mechanisms; Strengthening mechanisms; Phase diagrams, heat treatment; Ferrous and non-ferrous alloys; Ceramics; Polymers and Composites. GENERAL INFORMATION Students should attend all classes on time. An excessive number of absences will hurt student grades, especially the class participation portion. It is the responsibility of the students to get all lecture notes. Engineering Material ASSESSMENT AND EVALUATION Many aspects of the course will receive on-going, real-time assessments and feedback to help improve students’ performance. This will be done by discussing performance in class and by arranging individual meetings.
