Stress and Deformation: A handbook on tensors in geology by Gerard Oertel
Despite 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.
Research experience from a physicist
Just back from Prof. Mahir Hussein's seminar. He is really one of best physicist I have ever met. In past 30 years, he published more than 200 papers in the field of nuclear resonance, laser accelerated particles etc. There are more than 30 papers published in PRL alone. When input his name " M.Hussein" in arXiv.org, you can easily found 95 papers by him.
ES 240 student fall 2007
My 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.

Learning to be a PhD advisor
We professors usually start our jobs unprepared. In our days as students, we are considered talented if we can solve problems posed by our professors. We might be even considered brilliant if we can solve them quickly and make a few extensions. After solving a few such problems, we write a thesis. We are then entrusted with a job as a professor. We soon realize that the skill of solving problems posed by others only plays a minor role in our jobs.
Boundary Element for Cavity Problem
Dear BEM experts:
I am trying to find a boundary element solution for the problem of a cavity in an infinte space. The boundary condition is such that the cavity boundary is subjected to a constant radial influx. I have used the standard fundamental solution for the interior case (finite domain). The results, I obtained for the potential were reasonable for points inside the exterior region. However, on the boundary, the results for the potential were in the order of 10^12 (instead of zero value)!! Any idea what went wrong. Thanks. Husain

ES 240 Problem 6
I 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.
