Description: Mechanical behavior of materials and analysis of stress and deformation in engineering structures and continuous media. Topics include concepts of stress and strain; the elastic, plastic, and time-dependent response of materials; principles of structural analysis and application to simple bar structures, beam theory, instability and buckling, torsion of shafts; general three- dimensional states of stress; Mohr’s circle; stress concentrations. Lectures, recitations, and laboratory.

         Prerequisite: ENGN 0030.

            ENGN 0040 is not explicitly required but if you have taken 0040, it will help you a lot.

Textbook: “Solid mechanics in engineering”, by Raymond Parnes (Wiley). Required. We will assign problems from this book. Note that the level of mathematics in this book might seem a bit higher than what you are used to. Don’t panic! We will make sure you are sufficiently prepared to get through this course. Our course will be designed around this book, and the chapters we are covering, with approximate dates, are on the course calendar.

   

    Below are some other books that you should know about. If you are having trouble with a particular concept sometimes it is useful to read about it from another point of view.


     1.“Mechanics of materials”, by Beer, Johnston, DeWolf, Mazurek (McGraw-Hill, many editions). Commonly used undergraduate engineering textbook. Not as much of a focus on the fundamentals as our textbook. There are many other similar textbooks in the library or on the market.


Homework: Problem-solving is crucial for this class. It is to your benefit to do the homework since (1) it will help you on the exams, (2) there will be a problem on each exam which is very similar to a homework problem that has been assigned, (3) if you don’t do the homework, your grade will suffer, and (4) if you are on the borderline between A and B or B and C or C and NC, good homework might push you up. As the schedule allows we will assign problems on material before we cover it in class, so that you will have grappled with the material before it is covered in lecture.


Homework Policies:

  1. Homework will be due weekly at 4pm on Fridays in a box in the secretarial bay outside Prof C. Franck’s office on the 7th floor of B&H

  2. Late homework will not be accepted. To account for illness, family emergencies, and sports trips, we omit the lowest homework grade when computing the final grade. Please don’t bother to ask for an extension on your homework—any one homework set contributes very little to your grade. But they are extremely important for your understanding.

  3. You are free to talk with anyone about the assigned problems. You are free to work out problems in groups, but the work you turn in must be your own.  You can look at other books or on the internet if you think it will help you. But please use good judgment—it is considered cheating to look at an internet site that collects homework solutions from textbooks and courses. There is evidence that students who simply copy solutions from sites like these perform more poorly than students who do not.


Exams:  There will be two in-class midterm exams, on October 16 and November 15. There will a final exam that is cumulative. If you have any special needs, please make sure to inform Prof. Christian Franck well before the exam time (send him an email or meet with him in the first two weeks of class).


Labs: There will be 2 labs to be performed this semester.  Each will require a separate report to be turned in after the completion of the laboratory component.  The format and the guidelines of the report will be given with the assignment.  Below is the rough schedule of the labs, although it is subject to change if we do not cover the necessary material in timely manner.  Lab reports will be turned in electronically (PDF format), no paper reports will be accepted.


    Lab 1: Uniaxial Strain Field Measurement.  Introduced in lecture 9/30, due 10/9 at 5pm.

    Lab 2: Soda Can Myth Buster.  Introduced in lecture 10/28, due 11/6 at 5pm.


Plagiarsm: Plagiarism will not be tolerated.  This includes, but is not limited to, copying other students work, solutions manuals, or internet sources, misrepresenting work as your own by not properly citing or referencing sources, or including your name on a lab report that you did not contribute to. More information on the Brown Academic Code can be found here: http://www.brown.edu/Administration/Dean_of_the_College/curriculum/academic_code.php.  Any questions regarding this topic will happily be addressed by the course faculty and TAs.


Design project: There will be a design project that introduces students to the powerful mechanics software, ABAQUS.  The project will be at the end of the semester because it utilizes all the concepts and skills you have developed though out the course.  It will be introduced in class on 11/18.  Part I (analytical) will be due on 11/27 at 12pm.  Part II (computational) will be due on 12/11 at 5pm.  More details will be give out in class.


Grading:  Your final grade will determined based on the following:


2 midterm exams:             40% (20% each)

Final exam:                        30%

Homework:                       10% (lowest HW grade dropped)

Labs:                                  10%

Design Project:                 10%
