Dear Prof/Dr/Colleagues,
With great pleasure and respect to all Prof(s) and Dr(s),
It gives us great pleasure to announce regarding to a new monthly journal publication and online, in Multidisciplinary Sciences, IJFPS.
IJFPS is appreciating, if you submit one of your valuable papers.
IJFPS is your journal and expected to publish in JUN-2011.
IJFPS is hoping for your kind response.
IJFPS is waiting for your submission.
Hi,
I have a question and would be grateful if you could drop me some lines for it:
1- Is sound (or ultrasound) is ONLY generated when a structure is vibrating at its resonance frequency?
2- If the answer to the above question is YES, is sound (or ultrasound) generated at all resonance frequencies or just some of them depending on the amplitude of the vibration.
Thank you,
Babaei
I HAVE PROBLEM IN MAKING CONTACT ANALYSIS IN ANSYS. IT IS TOO MUCH HIGH AND CAN NOT MATCH WITH HERTZIAN CONTACT STRESS. SO PLEASE HELP ME.
Hi there, I'm kind of new in iMechanica despite that I've registered for more than one year. I've read many posts containing helpful information, but never posted my own until now.
Dear Friends,
I have developed a ser of 2-D finite elements for the problems of structural mechanics. These two dimensional elements are capable of accurately predicting three dimensional stress states using three diemnsional constitutive law. My doubt is: can these elements be used for the analysis of 3-D crack propagation using XFEM?. The displacements chosen for these elements are simple.

PRL 106, 248302 (2011) The atomic scale lithiation mechanism of individual SnO2 nanowires in a flooding geometry was revealed by in situ transmission electron microscopy. The lithiation was initiated by the formation of multiple stripes with a width of a few nanometers parallel to the (020) plane traversing the entire wires, serving as multiple reaction fronts for later stages of lithiation.
