I would like to share our recent paper "Delayed detached eddy simulation-based aerothermoelastic analysis of deployable control fin in supersonic and hypersonic flows" published in Physics of Fluids. In this paper we study the stability and mechanics of a deployable control fin in supersonic and hypersonic flows accounting for fluid-structure interactions and joint freeplay nonlinearity. 

We investigate the fluid-elastic instability of a square tube bundle subject to two-phase cross-flow. A dimensional analysis is carried out, leading to a new criterion of instability. This criterion establishes a direct link with the instability thresholds in single-phase flows. In parallel to the dimensional analysis, experimental work is carried out to i) determine the instability thresholds in single-phase flows (new relation between the Scruton, Stokes and Reynolds number), ii) to test the validity of the two-phase flow instability criterion, derived from the dimensional analysis.

Our upcoming webinar is on September 27 at 2pm central.

Date/Time: September 27; 2-3pm CDT

Call for nominations for John J. Montgomery Award for Distinguished Innovation in Aerospace. This New Award Commemorates John Montgomery, Inventor of the human-piloted glider, a father of aviation. Deadline to submit is October 1, 2023. Details can be found at
John J. Montgomery Award for Distinguished Innovation in Aerospace - ASME.

We are seeking a highly motivated and enthusiastic candidate with background in continuum/experimental mechanics eager to be part of an exciting new research project: High strain rate behavior of thermoplastic composite materials for cryogenic hydrogen storage (H-FROST).

 Summary:

Our new paper is online in Journal of Applied Mechanics. We exolore the thermomechancial coupling in polydomain liquid crystal elastomers. https://asmedigitalcollection.asme.org/appliedmechanics/article/doi/10….

During next week, on September 14-15, we hold a pyLife workshop at the FME Czech Technical University in Prague, Czechia. pyLife is a Python-based open-source library built previously mostly by colleagues from Bosch to deal with the fatigue life estimation (see https://github.com/boschresearch/pylife).

EML will re-launch the EML Webinar Series (Young Researchers Forum) on 12 September 2023.  The webinars are planned to be held once a month for a total of 10 to 12 webinars per year. 

EML Webinar (Young Researchers Forum) on 12 September 2023 will be given by Ruobing Bai at Northeastern University via Zoom meeting
