There are 5 modules in this course

In this week, we will first provide an overview on the course's content, targeted audiences, the instructor's professional background, and tips to succeed in this course. Then we will cover critical material properties in design, such as strength, modulus of elasticity, and the coefficient of thermal expansion. A case study examining material selection in a Zimmer orthopedic hip implant will demonstrate the real life design applications of these material properties. At the end of the week you will have the opportunity to check your own knowledge of these fundamental material properties by taking Quiz 1 "Material Properties in Design."

In week 2, we will review stress, strength, and the factory of safety. Specifically, we will review axial, torsional, bending, and transverse shear stresses. Please note that these modules are intended for review- students should already be familiar with these topics from their previous solid mechanics, mechanics of materials, or deformable bodies course. For each topic this week, be sure to refresh your analysis skills by working through worksheets 2, 3, 4 and 5. There is no quiz for this week.

In this week we will first cover the ductile to brittle transition temperature and stress concentration factors. Then, we will learn two critical static failure theories; the Distortion Energy Theory and Brittle Coulomb-Mohr Theory. A case study featuring the ultimate load testing of the Boeing 777 will highlight the importance of analysis and validation. Be sure to work through worksheets 6, 7, 8 and 9 to self-check your understanding of the course materials. At the end of this week, you will take Quiz 2 “Static Failure.”

In week 4, we will introduce critical fatigue principles, starting with fully revisable stresses and the SN Curve. Then, we discuss how to estimate a fully adjusted endurance limit. Finally, a case study covering the root cause analysis of the fatigue failure of the Aloha Airlines flight 293 will emphasize the dangers of fatigue failure. In this week, you should complete worksheets 10, 11 and 12 as well as Quiz 3 “Fully Reversed Loading in Fatigue.”

In this last week of the course, we will cover the fatigue failure criteria for fluctuating and randomly varying stresses, including key concepts such as the Modified Goodman line and Miner’s Rule. This week be sure to complete worksheets 13 and 14 as well as Quiz 4 “Fluctuating Fatigue and Miner’s Rule.” Finally, take Quiz 5, “The Comprehensive Quiz”, which will measure your overall knowledge of this course.
