Course Objectives:

This is a course for undergraduates dealing with the mechanical behaviour of metals, ceramics, polymers and composites. This course focuses on the stresses and strains in materials and the resulting deformation/fracture response.

Course Content:

Understand various types of deformation and failure of engineering materials subjected to various static and dynamic loadings. Correlate microscopic and macroscopic material behaviors. Obtain hands-on-experience with standardized mechanical testing techniques and learn how to present/interpret the measurements in a formal report.

Course Methodology:

1: Lecture by instructor, 2: Lecture by instructor with class discussion, 3: Problem solving by instructor, 4: Use of simulations, 5: Problem solving assignment, 6: Reading assignment, 7: Laboratory work, 8: Term research paper, 9: Presentation by guest s

Course Evaluation Methods:
