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.
Hello All
I am trying to read the text book Tensor analysis by IS Sokolnikoff and stuck in
chaper 1, there is some confusion in my mind regarding orthogonal transformations,
change of basis and and a transformation representing deformation of space.
Please bear with me if my confusions are unfounded.
1) Is is safe to say that transformation representing deformation of space acts on
vectors where as transformations representing the change of basis acts on
components?. (if yes then the following questions are resolved and need not be
looked)
2) Sokolnikoff builds up the reasoning for orthogonal transformations based on
deformation of space (i.e orthogonal transofrmations keep the length of vector
I'm working with multiple meshed items and attempting to cut them using the Instance boolean operation. My parts include parts I've sketched & meshed in Abaqus and a 3D object I imported from MIMICS (.inp file). When I attempt to selectively cut the instances that overlap, Abaqus failed. Any suggestions on the modeling of bone and implant with a reasonable fit in geometry?
