PhD Positions Available (up to 2) on Fatigue Resistance of Bone

Submitted by b.gludovatz on

Bones not only support and protect the various organs of our body but provide structure and enable mobility making them the most important structural materials in the human body. While aging, diet and health are known to significantly affect the structural integrity and fracture resistance of bone, fatigue, a significantly more important loading condition, is rarely studied.

Sandia Fracture Challenge: Survey

Submitted by Sharlotte Kramer on
The Sandia Fracture Challenge (SFC) was issued in December 2016, and the SFC supplemental information became available in February 2017.  The predictions are due July 15th, 2017.  We would appreciate feedback from you regarding the Challenge prior to the return of the predictions.  
 

Sandia Fracture Challenge Update

Submitted by Sharlotte Kramer on
Supplemental information for the third Sandia Fracture Challenge (SFC) is now available!  We have compiled the supplemental information promised in the original information packet and some additional information based on questions we received from participants.  The supplemental information includes electron backscatter diffraction (EBSD) data on the Challenge geometry, additional base material tests, raw DIC images and examples of DIC analyses of base material tests, and additional boundary condition information.

The 3rd Sandia Fracture Challenge is here!

Submitted by Sharlotte Kramer on

The third Sandia Fracture Challenge is here!  We invite to you participate in this next installment of our collaborative, blind assessment of predictions of ductile fracture.  For the third SFC, we wanted to challenge the computational mechanics community to predict ductile fracture in an additively manufactured structure.

Is energy conservation satisfied in the current deformation application schemes in molecular dynamic simulations?

Submitted by Fan Yang on

In our recent paper, we examined the energy conservation for the current schemes of applying active deformation in molecular dynamics (MD) simulations. Specifically, two methods are examined. One is scaling the dimension of the simulation box and the atom positions via an affine transformation, suitable for the periodic system. The other is moving the rigid walls that interact with the atoms in the system, suitable for the non-periodic system.

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!).
