Plasticity

Multi-scale finite element modelling of magnesium medical devices

Submitted by pmcgarry on

Applications are invited from suitably qualified candidates for two full-time Postdoctoral Researcher positions on the finite element simulation of magnesium orthopaedic implants. These three year fixed term positions are funded through a US-Ireland R&D Partnership Programme involving collaboration between the SFI Centre for Research in Medical Devices (Cúram), the NSF Engineering Research Centre Revolutionizing Metallic Biomaterials (RMB, USA), and the Nanotechnology and Integrated Bioengineering Centre (NIBEC, Northern Ireland).

Interested candidates should send a CV to patrick.mcgarry@nuigalway.ie

The start date for both positions is September-November 2017.

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.

Drucker Prager Plasticity model

Submitted by setareh on

Hi All,

I am trying to code the Drucker prager plasticity model for the 2D plane strain case using consistent tangent modulus. I am using C++, therefore I would appreciate if anyone could share relevant materials which I could use and preferrably for the 2D case so it is not unnecessarily complicated.

 

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.
