Final Exam Results

A slide is attached that summarizes the results of the final exam.  Based on the responses to the first 10 "conceptual" questions, it was pretty clear to me that a number of you did not understand some of the concepts from this class.  I would highly encourage each of you to provide a thorough evaluation of the course using the on-line system and let me and the department know what could have been done to improve your ability to understand the course information, what kinds of background you felt you didn't have coming into the course that limited your performance on homework assignments and exams, etc.  Please try to be as constructive as possible -- complaining about the course isn't particular helpful if you don't provide some suggestions (for example, suggestions based on more positive classroom experiences) .  Thanks.

Final Exam

The final exam is attached.  I will be posting the solutions and then the results in subsequent posts, since it does not appear that the system allows more than one attachment at a time.

Final lecture notes - take 2

Looks like the blog didn't like me adding an attachment, so the last post only appears to have the syllabus and not the lecture notes.  I am reattaching to this post.

Final lecture notes

Lecture notes from last night's final lecture are attached.  Note that on the first and last slide (syllabus slides), the lecture is associated with "handouts".  The "handouts" are just these lecture notes.  Interested readers can find much of the information from the lecture in the book by I. M. Ward and D. W. Hadley listed on the full syllabus, which is also attached.  There is also some information on linear viscoelasticity in the Dowling book, chapter 15.

Question on Chapter 13 homework assignment

I received the following question via email:

I am a little confused about how to deal with Ramberg Osgood stress strain curves when trying to set up a curve for moment versus edge strain and I have a similar problem with Torsion. Is it possible to break the Ramberg Osgood curve into an elastic section and a power hardening section, or does equation13.27 (the one with Beta's) have to be used? If equation 13.27 is the right way to go, how is it possible to eliminate yield stress from the equation and make the expression a function of edge strain?

Answer: 

You don't have to have an explicit equation to make the plot.  You have eq 13.27 relating M to edge stress, and then you have the ramberg-osgood equation, which you can use to calculate edge strain from edge stress.
