Generation of Sound (or Ultrasound) Waves & Resonance

Submitted by Babaei on

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

 

3-D crack propagation using 2-D dimensional finite element

Submitted by psubbu2000 on

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.

Multiple-Stripe Lithiation Mechanism of Individual SnO2 Nanowires in a Flooding Geometry

Submitted by Jianyu Huang on

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.
