COURSE OBJECTIVES
The central theme of this course is the mechanical behavior of engineering materials, such as metals, ceramics, polymers, and composites, subjected to different types of loading. The main objectives are to provide students with basic understanding of phase transformation by heat treating and stress-induced hardening, linear and nonlinear elastic behavior, deformation under multiaxial loading, plastic deformation and yield criteria, dislocation plasticity and strengthening mechanisms, creep, stress concentration effects, brittle versus ductile fracture, fracture mechanisms at different scales, fatigue, contact deformation, and wear.
DESIRED COURSE OUTCOMES
Understand various types of deformation and failure of engineering materials subjected to various static and dynamic loadings. Correlate microscopic and macroscopic material behaviors. Learn how to engineer the material properties to meet certain specifications. Determine the safety factor for various possible failure modes and loadings. Obtain hands-on-experience with standardized mechanical testing techniques and learn how to present/interpret the measurements in a formal report.

CONTRIBUTION OF THE COURSE TO MEETING THE
PROFESSIONAL COMPONENT
Students learn the importance of the strength of materials in various engineering disciplines, specifically the design of large- and small-scale mechanical components. The course will also provide students with the ability to identify, formulate, and solve problems related to the behavior of engineering materials, obtain engineering and communication skills, and use methods and mechanical testing approaches for engineering practice.
RELATIONSHIP OF THE COURSE TO ABET PROGRAM OUTCOMES
An ability to apply knowledge of mathematics, science, and engineering. An ability to identify, formulate, and solve engineering problems. An understanding of professional and ethical responsibility. An ability to communicate effectively. An ability to use the techniques, skills, and testing methods necessary for engineering practice.
ASSESSMENT OF STUDENT PROGRESS TOWARD COURSE OBJECTIVES
Homework assignments on a weekly basis. Laboratory assignments (approximately one assignment every 2-3 weeks requiring a written report). Midterm examination. Final examination.
