## Stress and Deformation: A handbook on tensors in geology by Gerard Oertel

Tue, 2007-10-16 14:07 - AlisonForsythDespite the title, the book covers very little specifically on geology. It works through stress, strain, and other tensor quantities, but assumes you know little about the math. Fully worked problems make up the bulk of the book following a few introcutory chapters. I've found it a nice review of the math, but haven't fully explored the solution sections. I got the book from Cabot Science Library here at Harvard. I wouldn't recommend buying it on amazon it's not worth the $72, but it is a nice addition to Timoshenko's theory of elasticity.

## ES 240 student fall 2007

Thu, 2007-10-11 20:38 - mingguoMy undergraduate and master major is engineer mechanics. I have took several courses about this field, like theory of elasticity and mechanics of materials. But my major during master degree is plant bio-mechanics, especially the role of water surface tension and water transport. So I deeply feel that I need to learn solid mechanics again. That is why I choose this course.

## SOLID MECHANICS POST

Fri, 2007-10-05 10:05 - Nathan Thielen
Solid mechanics was at the top of my course list because of my interest in

strength of

materials. Prior courses in solid mechanics include undergraduate mechanics of

materials and an introduction to solid mechanics course. Mechanical engineering

was my undergraduate major. My main weakness related to this course is the

ability to take a real world problem, which is not spelled out and correctly

apply the theories learned in the course. My primary strength related to this

## ES 240 - Sun Min Jung

Fri, 2007-10-05 02:58 - Sun Min JungHi, my name is Sun Min Jung and I am pursuing a Master of Science in Engineering Sciences. Thus I do not belong to a research group, but I am interested in doing research next semester for a 299r. I will be going into industry as a stress engineer, so this course will prepare me to have the necessary background for the job, as well as prepare me for a 299r next semester.

## ES 240 Problem 6

Fri, 2007-10-05 00:46 - Yuhang HuI took the course of Theory of Elasticity during my undergraduate study and the course of Finite Element Method during my master's study. And my major is Engineering Mechanics. Therefore, I have some fundamental knowledge in solid mechanics but not enough, since I have no background in the aspects of plasticity and large deformation theory. I am currently doing research under Professor Suo's group (http://www.seas.harvard.edu/suo/) and my research topic will focus on gel which is a kind of soft material.

## HW 2 Problem 6

Thu, 2007-10-04 23:35 - Eric D. KiserMy name is Eric Kiser. I am part of the seismology group at EPS. I am currently working on a back-projection method for imaging earthquakes. My undergraduate major was in geology at the University of Illinois. Some of the topics we are covering in ES 240 I have seen in my undergraduate geophysics classes. I'm hoping to obtain a better understanding of stress and strain from this course, so I can apply it to physical properties within the Earth.

## Pset 2 Problem 6

Thu, 2007-10-04 22:20 - Adam TrainaHi everyone

- my prior courses are mechancis of materials (ES 120) and intro to material science (ES 190)

- I am pursuing Harvard's co-terminal AB/SM degree, and have finished my undergraduate requirements in engineering scinces with a focus on Mechanical Engineering

- A definate plus is having taken the undergraduate class only a few years ago, and having much of the material presented in a very similar style which i have grown accustomed to. My weakness is always the math.

## ES 240 Problem 6

Thu, 2007-10-04 22:06 - Cai ShengqiangI have got the master degree of Solid Mechanics in University of Science and Technology of China. Actually, I have taken several courses related to this subject, such as strength of materials and the theory of elasticity. So, my strength may be that I have some knowledge about it, but my poor ability to solve PDE or even ODE could be the specific obstacle for studying this course. I will do research in Suo’s group(http://www.seas.harvard.edu/suo/), and my research may be related to soft matters, such as gels.

## ES 240 Problem 6

Thu, 2007-10-04 21:38 - Maria Persson GuldaMy name is Maria Persson Gulda. I am a first year grad student at Harvard. I did my undergrad in Engineering Physics, with a minor in Applied Math, at University of Colorado at Boulder.

The classes from my undergrad that are closest related to this course are Classical Mechanics and Solid State Physics. I think my strength in ES 240 will be my applied math knowledge and my weakness will be my lack of courses in mechanics and/or materials.

## Response to Problem 1 on Problem set 2

Thu, 2007-10-04 17:55 - Kathleen W. DiSantoIn terms of my background, I have taken two courses relating to solid mechanics. The first course was Mechanics of Deformable Bodies, which was an introductory strength of materials course. I have also taken a course called Aerospace Structures. In this course, the first half was devoted to elasticity and the second portion of the course was about solving problems relating to failure in aircraft. We were also introduced to Finite Element Analysis and performed labs using FEA software.

I majored in Mechanical Engineering as an undergraduate.

## ES 240 Problem 6 Blog Entry

Thu, 2007-10-04 10:52 - John Peter WhitneyMy name is John Peter Whitney, but I go by Peter. My parents set it up that way--I don't know why. This is my answer to Pset 2, problem 6:

* I last took solid mechanics Fall 2001. This sophomore-level course was taught by Professor Mark Spearing. We used Crandall, Dahl, and Lardner. I have forgotten almost everything from that class.

* My undergrad degree is in Physics, and my masters is in aerospace engineering (which I also studied but did not get a degree in as an undergrad).
