Defects and Fracture Mechanics

In this video, Daniel Trias Mansilla explains the fundamental differences between brittle materials like glass and ductile materials like metals. While typically seen as brittle and fragile, glass has become a reliable structural material thanks to advancements in engineering and manufacturing. The key difference is that ductile materials can absorb energy through plastic deformation (bending without breaking), providing a safety warning before failure. In contrast, brittle materials like glass cannot deform plastically; they can only dissipate energy through crack growth. The strength of glass is not determined by its atomic bonds but by the presence of small defects like surface scratches, edge flaws, or inclusions. These defects cause a "stress singularity," where stresses become theoretically infinite at the tip of a sharp crack, making traditional stress analysis unreliable. The field of Fracture Mechanics is used to understand how cracks behave under different loading modes (I, II, and III) and to design and predict the load-bearing capability of glass. To improve strength, engineers must understand this relationship, and manufacturers must work to reduce the number and size of defects in the glass. The video was produced by the Open GLASSroom project. Special thanks to Daniel Trias Mansilla for contributing to the Open GLASSroom OER collection.

Unit 2: Taking a critical stance, using sources and avoiding plagiarism [LIBRARY TUTORIAL; assignment koppelen]

Videos: Video 3: The role of sources Video 4: Why we cite & Plagiarism Homework task(s): Complete Assignment 1: Library Tutorial (Ask your own library, or see this example: https://search.edusources.nl/materialen/fb8124eb-52bc-42ef-95fc-0db6bce4bfba) Complete a draft of Assignment 2: Critical Reflection (See Teacher’s Handbook for the Academic Reading and Writing module) Suggested tasks for the tutorial: Discussion questions to detect bias (positive or negative) in [introductory text] • Is the author a known expert in the field or topic, with a background and credentials that can be easily verified? • Does the author use strong or emotional language, present opinion as fact, or employ the use of stereotypes in order to express his or her attitudes? • Does the author present information gathered from source materials both accurately and within the proper context? • Are there any flaws in the selection of source materials, the performance of analysis, or the design of methodology, which might suggest a deliberate attempt to satisfy or support a predetermined argument, outcome, or opinion? (Source: HSU Resource Database) Discussion questions on using sources and avoiding plagiarism • Why do we use sources? • What is citation and why do we do it? • What is plagiarism? What can you do to avoid it? Class quiz to explore plagiarism For each scenario below, decide whether it is a case of plagiarism [answers in brackets]: • Copying some of the work of one of your classmates [YES] • Copying and pasting from a source, citing the source, but not using quotation marks [YES] • Translating a part of a non-English article (e.g. in Chinese or French) and not giving a citation [YES] • Using information that constitutes general knowledge, and not giving a citation [NO]
