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.

Lehrplan - Was Sie in diesem Kurs lernen werden
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.

Top-Bewertungen von MATERIALS SCIENCE: 10 THINGS EVERY ENGINEER SHOULD KNOW
This course helps me in learning about the stress -strain curve and the mechanical properties of different materials and the tests to find the mechanical properties that a material can with stand.
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.
A special thankd to Mr.James Shackelford, who guided me throughout this course journey. The way he explain all material science topic is fablous. I enjoyed this course and once again i thank you sir
I really enjoyed this course. I was not sure what to expect but it was very informative and I learned alot of crucial lessons that I supposed to know working in automotive industry. Thank you :)
