Crack Propagation in Bamboo's Hierarchical Cellular Structure
Bamboo, as a natural hierarchical cellular material, exhibits remarkable mechanical properties including excellent flexibility and fracture toughness. As far as bamboo as a functionally graded bio-composite is concerned, the interactions of different constituents (bamboo fibers; parenchyma cells; and vessels.) alongside their corresponding interfacial areas with a developed crack should be of high significance.

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)
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!).

Call for abstracts: “Issues in computational modeling of damage, fracture and fragmentation of solid materials”
As part of the 51st Annual Technical Meeting of the Society of Engineering Science (SES 2014) to be held at Purdue University, West Lafayette, IN, on October 1-3 2014, it is our pleasure to invite you to submit an abstract to the Symposium “Issues in computational modeling of damage, fracture and fragmentation of solid materials”.
What are the regular iteration steps of cohesive model based FEM for crack problems
Hi,
I'm now start to learn cohesive zone model based FEM for crack problems. According the a regular coehsize model (bilinear for example), the relative displacement and the cohesive stress are both unknwon, so iteration is required. My question is that what are the regular iteration steps?
Thanks.
