recitation will outline the lab activities and schedule in detail In short you will attend lab 9am 1pm on EITHER Tuesday or Thursday of a given lab week as indicated on the 3 032 calendar You will attend recitation on the day T or R that you do not have lab that week Lab 1 Stress transformations and pressure vessels Lab 2 Atomistic origin of elasticity Lab 3 Micro and nanoscale plasticity Lab 4 Uniaxial mechanical testing Week of 9 17 Week of 10 15 Week of 11 5 Week of 12 3 Everyone goes to recitation this Thursday 10am in 3 442 Images removed due to copyright restrictions Please see http

TO READ AND LEARN MORE Textbooks Required 3 032 Course Reader Mechanical Behavior of Materials Available at CopyTech 3 011 63 Recommended Supplementary Hosford Mechanical Behavior of Materials Note There are many texts that treat various aspects of mechanical behavior However these texts tend to treat either the mechanics or the materials perspectives well rather than integrating the two Your lecture notes provide this integration and the Course Reader provides sufficient background material and worked examples from the best textbook for a specific topic The Hosford text is recommended and heavily cited in the Course Reader but is missing key material covered in the first third of the class MIT Server Website Bookmark the class website here you will find the assigned problem sets and laboratory materials as well as resources such as material property databases practice material for quizzes and scientific and general audience articles that include content related to our class topics 3 032 Mechanical Behavior of Materials Fall 2007 IV HOW IS MY UNDERSTANDING EVALUATED Grading 1 Breakdown Quizzes 3 Problem sets 7 Labs 4 15 each Fri 10 5 Fri 11 9 TBA on week of 12 17 25 total 30 total 2 Academic Honesty We encourage you to work together on problem sets and lab analysis discussion However all work turned in must be your own product as it stands on the submission due date What is cheating Duplication of others problem set solutions figures summarizing lab data or quiz responses is cheating Failure to cite sources of ideas and or facts in your problem sets and laboratory written assignments is cheating Falsifying excuses for late missing assignments or lab participation is cheating Backdating alteration of submitted documents and false claims that electronic files have been submitted by the due date are cheating A student who cheats will receive a formal letter in his her file at the Office …
