I suppose it is acceptable to announce the work I have online to assist students in learning mechanics and thermo. The site is http://www.askdrthermo.com/. Please take a look if you are interested.
Hi All, thanks in advance for any replies.
I am currently doing my Thesis on fast stress analysis using the boundary element method and specifically, adaptive cross approximation. I ofter come across the terms "single layer potential" and "double layer potential", i "know" what they are mathematically, i was wondering if anyone could give me an insight into what they mean physically, or just give a simple non mathematical definition? Thanks a lot, Ian.
Hi everyone,
Does anyone have the work experience on stepped column kind of structure?
I would like to know, how to determine the crippling load for stepped column kind of structures? If anyone have the materials pertaining to the subject, please do share (if interested).
Thanks and Regards

In our wind tunnel experiments, we have wake survey of a cylinder and boundary layer measurement for a thin flat plate as two experiments. We measure the stagnation pressure(Pt) at points using a pitot tube. We also measure the static pressure of the free stream Pinf.
Hello everyone,
Why do we have the infinitesimal (linear) strain tensor to be symmetric? The reasons, which I have understood so far are:
1. It is defined to be symmetric so that it behaves like a tensor.
2. The stress tensor, which is its energy conjugate, is symmetric, and hence the skew-symmetric part has no contribution towards strain energy.
Can anyone suggest more fundamental reason(s) for the symmetry of linear strain tensor, like the moment equlibrium leading to symmetry of the Cauchy stress tensor?
Thanks in advance,
I have updated sections of my notes on thermodynamics. A few thoughts on learning are collected here. Of our world the following facts are known:
Dear all
I'm doing an analysis where i need to evaluate the contact area acoording to hertz theory.
I have a book which shows me every step, except for how to calculate two coefficients, and insteads gives me a table of calculated values.
For the contact patch dimensions a and b, i get the expression
where i need to determine m and n. My book (A swedish book without ISBN) simply states that m and n are functions of theta,
and writes a large table with m and n for different angles
Hi Suo and other guys,
I am Chennakesava. I am new to this site. I have completed my Masters in Mechanical Engineering from Indian Institute of Technology, Kanpur, India. (IITK) . Year of study is 2006-08. My specialization is Solid Mechanics & Design. Right now am working in GE, India. I want to pursue doctoral degree in the field of Dynamics and Vibrations and related issues like, Rotor dynamics, Smart structures, MEMS, Nonlinear dynamics and Chaos. Its kind of a dream to me.
