Dear Colleagues,

I am sharing a preprint on using first-principles simulations for gaining new insights into the thermomechanical processing of magnesium alloys. 

Title: Influence of thermomechanical loads on the energetics of precipitation in magnesium aluminum alloys

 Authors: Swarnava Ghosh and Kaushik Bhattacharya

Here is the link to the manuscript: https://arxiv.org/abs/1912.11434

Sincerely,

Swarnava

Hi,

I am trying to use iso-geometric elements in LS-Dyna with the keyword *ELEMENT_NURBS_SHELL_PATCH. The job manager terminates without mentioning where the errors are.

Can someone help me with this? A sample .k file using the above keyword will be helpful.

Thank you!

Regards,

Harsha Reddy

Dear Colleague,

In case you are getting tired of the holiday fare, you might enjoy a recent paper, coauthored with Nate Goldberg, on modeling the mechanics of spaghetti cooking that has just been published in Physical Review E:

The Department of Mechanical Engineering and Applied Mechanics at Penn has an open search for tenure-track/tenured faculty.  We are particularly interested in candidates whose work is at the intersection of mechanical engineering and computational science. Additional details in the attached PDF file. Apply at: https://apply.interfolio.com/71186

Note: This ad was posted on multiple sites this past Fall but didn't appear on iMechanica.  As such, the deadline is quickly approaching and is January 7.

COHMAS Laboratory at KAUST (King Abdullah University of Science and Technology) will host on March 16-18 a high-caliber workshop aiming at discussing the latest developments in Composite Science and Engineering.

The Advanced Manufacturing and Energy Lab (AMEL) directed by Prof. Yanliang Zhang at the University of Notre Dame (A top 15 University in US) have multiple fully-funded graduate student opening positions with full tuition coverage plus a competitive stipend. The AMEL is working on cutting-edge research topics including additive manufacturing and scalable nanomanufacturing of functional devices and autonomous systems, thermoelectric energy conversion, flexible electronics and human-machine interface. Interested applicants should send resume to Prof.

ThermoElastic Instabilities (TEI) occur in sliding bodies at sufficiently high speed because a small thermoelastic disturbance tends to localize the contact, leading to “hot spots”. The role that wear plays in TEI has been studied briefly and only on highly idealized cases. We extend and complete in detail a model of Dow and Burton who studied the specific configuration of a blade sliding on a rigid halfspace normal to its line of contact. We find there is a limit value of wear coefficient, that can be estimated by simple equations, above which TEI is completely eliminated.
