Course Description EMA 4223 - Mechanical Behavior of Materials (3 credits)

Text: M. A. Meyers and K. K. Chawla, Mechanical Behavior of Materials, Prentice-Hall (1999).

Reference Texts: M.F. Ashby & Jones, Engineering Materials,1 & 2, Pergammon Press (1980).
R. Hertzberg, Deformation and Fracture of Engineering Materials, 3rd ed., Wiley (1989).
T.H. Courtney, Mechanical Behavior of Materials, McGraw-Hill (2000).
Prerequiste: EGM 3520 or equivalent.

Goals:

To introduce the student to problem solving techniques which involve structural materials in adverse mechanical and chemical environments. To demonstrate the common themes of mechanical behavior for different classes of materials.
At the end of the course, the student should be able to predict the failure mode and stress of materials subjected to flexural or tensile stresses in uniform or cyclic loading conditions. The student will be able to estimate the time under load for materials that exhibit creep and/or viscoelastic behavior. The student will be able to determine the failure mode and stress levels for plastic deformation and fracture in a brittle manner.
