Failure of Materials in Mechanical Design
EML 6934 Section 6572 (fall 1999)

This is the first course of a two-part series, which studies the failure of materials due to stresses, strains, forces, contact, and attack by the environment. As indicated in the title of the text itself, emphasis will be on failure analysis, prediction, and prevention. Although the course does not specifically cover design philosophy, the selection of materials based on the identification of likely failure modes and the supporting analysis will be frequently discussed. Course Syllabus Topic Date (week of) Overview of engineering materials Aug. 23 Introduction to stress, strain, and the relationships between stress and strain Aug. 30 The combined stress theories of failure Sept. 6 Homework Set 1 Due Introduction to fatigue and cyclic loading Sept. 13 High cycle fatigue Sept. 20 Cumulative damage and life predictions Sept. 27 Low cycle fatigue Oct. 4 Homework Set 2 Due Midterm Examination Oct. 11 Introduction to linear elastic fracture mechanics Oct. 18 Stress intensity factors Oct. 25 Elastic-plastic fracture mechanics Nov. 1 Homework Set 3 Due Creep and stress relaxation Nov. 8 Corrosion and effects of environment Nov. 15 Fretting fatigue and corrosion Nov. 22 Introduction to wear, friction, and surfaces Nov. 29 Homework Set 4 Due Final Exam Dec. 11 Text "Failure of Materials in Mechanical Design - Analysis, Prediction, Prevention," J.

Course Policy Professor: Greg Sawyer Office: 309 NSC Telephone: (352) 392-8488 E-Mail: wgsawyer@ufl.edu Office Hours: M,W 8AM-10AM, Tues 4PM-6PM Class Hours: M,W,F 11:45AM-12:35PM Homework Four homework sets will be assigned and graded. Two weeks are given for completion of a homework set. The purpose of the homework is to aid in learning the material. To this end, some collaboration among students in preparing the homework is acceptable. However, in the main, the work should be primarily yours. In an effort to increase the value of homework, solutions will be posted on the internet the day after it is due and discussed in the next available class period. Because of this tight time line, late homework will not be accepted. Exams There will be two tests, a midterm and final examination; these tests are open notes and open book. Grading Homework counts for 20% of the final grade (5% each), a lecture on material selection counts (20%), and exams count for 60% of the final grade (30% each). Attendance and Class Participation I consider attendance mandatory, and good class participation will be given consideration during the determining of final grades. Academic Integrity Following the recommendation of the Dean of Students, I include a statement on this topic. As is understood by the vast majority of students, our basic relationship is based on trust; I've only rarely seen problems in this area. Please familiarize yourself with the Student Guide, the honor code, and the implied pledge - which accompanies all work submitted for credit.
