Homogenization - If materials in the model are isotropic, is it possible to get truly anisotropic resulting material?
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?
The 2nd Sandia Fracture Challenge is here!
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!).
Drawing a 2D sketch on XZ plane in ABAQUS!
Hello All,
I am trying to make a 2D shell layer on XZ plane. To capture buckling of shell layer with 3-point bending load, I am required to model a 2D sketch on XZ plane. Modeling this way I can use shell elements' bending degrees of freedom. But ABAQUS always pick defauly XY plane to start with.
Does anyone know how to draw a sketch on XZ plane?
Thanks,
Jay Patel

J-integral contour path in ABAQUS
I have calculated the J-integral using ABAQUS for 5 contours but I could not find any information about the paths of the J-integral contours. Do you know how we can get the paths of the requested J-integral contours or equivalently how we can define the paths of contours in ABAQUS?
