Usually, taut helical strand bending is dealt with by decoupling axial load and bending analysis. In the attached report, based on a purely geometrical approach, it is shown that there is indeed some coupling, albeit small.
2.01x: Elements of Structures is a new introductory course in structural mechanics that just started on edX. Anybody can register to audit the course for free.
Course material includes lecture videos, tutorials, example problems, recitation problems with video walkthrough, homework problems, "boardnotes" (condensed lecture notes) and synoptic tables.
I would like to share with you our recent paper published in the Journal of Applied Mechanics: J. Appl. Mech. 81(8), 081010 (Jun 02, 2014)

Hello,
I read that "In general, even if the materials on the micro-level are isotropic, the effective
material can show anisotropic behavior. A general anisotropic linear elastic material
may have twenty one independent material parameters.''
If I understand my results correctly then simple structures like ''ball in the unit cell'' result in orthotropic material.
I am a bit puzzled - what would be the simplest structure that would result in anisotropic material behaviour?
Dear all,
Sometimes, we can see the conception of Mandel Stress, I wonder
What is mandel stress? How to use it?
Thanks.
update, 7/24/2014: The information packet ("SFC2-challenge-v5.ppt") is no longer attached to this post (iMechanica has a file size limit of 1 MB, so we can not attach the 6 MB file). IF YOU WOULD LIKE THE INFO PACKET, PLEASE E-MAIL ME, blboyce [at] sandia.gov and copy Dr. Sharlotte Kramer, slkrame [at] sandia.gov. If you have an older version of the information packet, please also e-mail for the newest (v5) info packet.
We intend to send the shear calibration data to all those whose e-mail address I have by August 1st (sorry for the delay!).
Dear everyone,
The third issue in 2014 (Volume 4, Issue 3) of Theoretical and Applied Mehcanic Letters (TAML) is now online.
Welcome to this young journal http://taml.cstam.org.cn for rapid publication of your exciting results.
