We explore “10 things” that range from the menu of materials available to engineers in their profession to the many mechanical and electrical properties of materials important to their use in various engineering fields. We also discuss the principles behind the manufacturing of those materials.

Course Overview / The Menu of Materials / Point Defects Explain Solid State Diffusion
Welcome to week 1! In lesson one, you will learn to recognize the six categories of engineering materials through examples from everyday life, and we’ll discuss how the structure of those materials leads to their properties. Lesson two explores how point defects explain solid state diffusion. We will illustrate crystallography – the atomic-scale arrangement of atoms that we can see with the electron microscope. We will also describe the Arrhenius Relationship, and apply it to the number of vacancies in a crystal. We’ll finish by discussing how point defects facilitate solid state diffusion, and applying the Arrhenius Relationship to solid state diffusion.

Dislocations Explain Plastic Deformation / Stress vs. Strain -The “Big Four” Mechanical Properties
Welcome to week 2! In lesson three we will discover how dislocations at the atomic-level structure of materials explain plastic (permanent) deformation. You will learn to define a linear defect and see how materials deform through dislocation motion. Lesson four compares stress versus strain, and introduces the “Big Four” mechanical properties of elasticity, yield strength, tensile strength, and ductility. You’ll assess what happens beyond the tensile strength of an object. And you’ll learn about a fifth important property – toughness.

Creep Deformation / The Ductile-to-Brittle Transition
Welcome to week 3! In lesson five we’ll explore creep deformation and learn to analyze a creep curve. We’ll apply the Arrhenius Relationship to creep deformation and identify the mechanisms of creep deformation. In lesson six we find that the phenomenon of ductile-to-brittle transition is related to a particular crystal structure (the body-centered cubic). We’ll also learn to plot the ductile-to-brittle transition for further analysis.

Fracture Toughness / Fatigue
Welcome to week 4! In lesson seven we will examine the concept of critical flaws. We’ll define fracture toughness and critical flaw size with the design plot. We’ll also distinguish how we break things in good and bad ways. Lesson eight explores the concept of fatigue in engineering materials. We’ll define fatigue and examine the fatigue curve and fatigue strength. We’ll also identify mechanisms of fatigue.

Meilleurs avis pour MATERIALS SCIENCE: 10 THINGS EVERY ENGINEER SHOULD KNOW
par ZMJul 17, 2017
This course is good for engineers. It illustrated many fundemental and important concept in materials science. The teacher is great who explain nearly everthings in details with words and experiments.
par NANov 23, 2016
It is a really good course. I would recommend it to everyone interested in materials or engineering. This course helped me get a better understanding of some fundamental concepts of engineering.
par SSJul 24, 2017
It helped me a lot to have a basic idea about different types of materials, processing and properties. I earned basic knowledge about materials and I can teach these relevant topics to students
par PCMar 4, 2018
This course was alot more educational then I thought it would be but now I compare what has shaped me in in life to creep deformation. I especially loved the lecture " a play on good and evil".
par SRMay 30, 2016
The course goes through all of the required topics within material science and gives proper information.\n\nProfessor's explanation and his description makes it easy to understand.\n\nThank You
par APJun 23, 2018
Beautiful course. Helped me a lot in the selection of materials for our rocketry team. I'll be sure to suggest this course to my fellow teammates. A big thumbs-up to UCDAVIS for this course.
par MPAug 19, 2017
I really enjoyed this course. I suggest everyone to have prerequisite knowledge in material science and metallurgy. It will be difficult to understand the lecture without prior knowledge.
par HRSep 8, 2019
It's a great refresher course for those who have undertook materials science as one of their subjects at school!!! It gave me a good foundation pursuance to study this at grad school.
par MAJan 22, 2016
The Course is designed so well by the UC Davis and Coursera. And the discussion forum is also really helpful for me while studying this course. It's really a great experience.
par YFFeb 13, 2019
pretty good, the professor deliver the lecture in a very vivid way and what really surprise me is that I can get so much knowledge from this short course.thank you, professor.
par MKJan 9, 2016
its been an awesome experience through the course. The topics have taught interestingly with relevant examples throughout the lecture's. Finally my sincere thanks to Mr.James
par DMAug 25, 2017
This course is meant for every engineer and one should take this course. It is very salient to engineering fields and consist varied subjects brief but essential knowledge.
