Hi, everyone,
I am new here. Now I am doing a research which is related to the Euler's buckling formula. It is known that when the cylinder is thick enough, Euler's buckling formula is no longer valid. I want to know in which region of slenderness(aspect ratio) of a cylinder or column that the Euler's buckling formula is valid. Is there any analytical study or numerical results about it? Is there any suggestion or paper I can find?
Thank you very much!
Dear everyone,
I am 26 years old and I got my master's degree this year. My research domains are receding horizon control for wheeled mobile robot, neural network and speech endpoint detection.
Now, I am searching for PHD position in Europe. I hope that somebody can give me some information.
Thank you.
Yours Sincerely
The fractal crack model described here incorporates the essential
features of the fractal view of fracture, the basic concepts of
the LEFM model, the concepts contained within the
Barenblatt-Dugdale cohesive crack model and the quantized
(discrete or finite) fracture mechanics assumptions. The
well-known entities such as the stress intensity factor and the
Barenblatt cohesion modulus, which is a measure of material
toughness, have been re-defined to accommodate the fractal view of
fracture.
Dear iMechanicians,
I wonder if anybody knows how to get an op2 file (MSC.Nastran) from MSC.Marc. Is something like that possible? Or do you know some available converter? Potentially, fil or odb file from ABAQUS or rst file from ANSYS could help as well. But I would expect there some way within the MSC product family...
Thanks a lot for any idea.

I'm stuck with this problem! I can't figure out how to start. Can some
one give me a guideline or tell me from which book this problem is??
I'm not good at mechanics(especially in dynamics). I always struggle in mechanics. Any solution to that!
The Department of Aerospace Engineering at Iowa State University invites applications for multiple tenure-track faculty positions at the assistant, associate, or full professor ranks to begin August 2009. Applicants are sought in all areas of aerospace engineering and engineering mechanics but preference will be given to those with interest and expertise in aerospace structures/mechanics of materials, multidisciplinary design and analysis, experimental thermal-fluids, propulsion, wind energy, and wind engineering.
