In a piezoelectric material an applied uniform strain can induce an electric polarization (or vice-versa). Crystallographic considerations restrict this technologically important property to non-centrosymmetric systems. It can be shown both mathematically and physically, that a non-uniform strain can potentially break the inversion symmetry and induce polarization even in non-piezoelectric dielectrics.
When you use a desktop software, such as Microsoft Word, to write an entry and then paste it to iMechanica, the format often looks bad. Instead, you can use Windows Live Writer to write blog post offline. Installation takes about 5 minutes. The Live Writer has a remarkably clean interface, and is very easy to use.
We invite you to participate in the upcoming Workshop on Materials Characterization for Nanoscale Reliability, to take place 14-16 August, 2007 at the University of Colorado in Boulder, Colorado. Details are posted at http://www.boulder.nist.gov/div853/Nanoscale_Reliability_workshop/index….
Given below is a sequence that might properly address the question of what to teach in the first (and the only) UG couse on strength of materials or solid mechanics.
0. Note: It's a mistake to believe that the contents for such a course can be covered in a linear fashion. Apply the spiral theory of knowledge and revisit certain concepts again and again: e.g., the concepts of stress, strain, fields, BV problems, theoretical structure, etc.
1. Introduction:
I wish that this thought had come to me earlier, so that I could have posted it on April First. No, I'm unaware of such a program. Instead, Harvard faculty have just emerged from a multi-year review of curriculum, and reaffirmed the commitment to liberal education, after voting out a president not too long ago.
Hi,
I am actually working of field data transfer techniques when remeshing is needed during analysis of metal forming process.
some
researchers use a so called Linear interpolation technique using the
volume coordinates as shape functions to transfer a field from a mesh
to an other.
Is there any one who used this technique in such a problem?
If there is any, could he tell me which are the advantages of the technique and its disadvantage?
Is there any tests to validate the method?
From Dr. Qizhi Xiao :
We are looking for several new permanent staffs, including software developers with solid background on mechanics and good programming skills. the detailed information about the posts can be found from
