Drexel and the Army Research Lab Forge a Partnership (for more details)
Drexel University researchers will now have the opportunity to work alongside scientists from the Army Research Lab — the Army’s central laboratory. The institutions recently signed an agreement that formally connects Drexel with ARL Open Campus research initiative. With this agreement, the University strives to engage a diverse and wide-ranging network of faculty in collaborative efforts with ARL entities.
“The Army will work closely with Drexel’s team lead by Professor Antonios Kontsos to formally address modeling approaches that can inform about the severity of damage precursors in aviation structures. The partnership also creates new experiential learning opportunities for students and connects them to career opportunities within the Department of Defense,” said Dy D. Le, chief of ARL-VTD’s Mechanics Division.
TAMG hosts the 58th Acoustic Emission Working Group (AEWG) meeting on Drexel’s campus in Philadelphia, May 22-25, 2016. We look forward to three days of engaging discussion of the state-of-the-art in Acoustic Emission.

Dr. Antonios Kontsos is named Assistant Director of the newly established Drexel Center for Functional Fabrics, during a university-wide town hall hosted by Provost Brian Blake.
Drexel University President John Fry opened and closed his first university-wide Town Hall meeting (link) of 2016 by praising the multidisciplinary team that made Advanced Functional Fabrics of America possible.
President Fry remarked:
“This was a really, really big moment for our University. In the six years I’ve been here, this is the single most important thing I’ve seen,” said President Fry. “We are competing against — and winning against — absolutely some of the best universities in the country. This was a long shot going in. But the best ideas and the best people won against the best universities in the country.”
04.01.2016 – Advanced Functional Fabrics of America becomes the 8th National Manufacturing Innovation Institute
The U.S. Department of Defense has tapped Drexel University as a key leader in the creation of a $75 million national research institute that will support American textile manufacturers in bringing sophisticated new materials and textiles to the marketplace. The institute, called Advanced Functional Fabrics of America (AFFOA), will be a national manufacturing resource center for industry and government to draw on the expertise of academic researchers working with new fibers, fabrics and materials and developing the technology that can integrate them into products from active wear to protective armor. Secretary of Defense Ashton Carter formally recognized AFFOA as one of the White House’s National Network for Manufacturing Innovation Institutes in a ceremony at the Massachusetts Institute of Technology. To view the livestream, follow this link here. Governor Tom Wolf of Pennsylvania highlights the Drexel team’s pivotal role in AFFOA at the 41 minute mark.

The article Microstructure-Sensitive Investigation of Magnesium Alloy Fatigue is accepted for publication in the International Journal of Plasticity!
“This article presents results relating macroscopic fatigue behavior to microplasticity, twinning activity, and early fatigue crack formation in wrought magnesium alloy specimens of the AZ series. Experimental data were obtained by testing standard-sized samples prepared to be also suitable for direct microstructural quantification using scanning electron microscopy and electron back scatter diffraction for texture, grain-scale observations and fractography, as well as surface morphology measurements using white-light interferometry. In addition, in situ nondestructive monitoring of the fatigue behavior was performed by using the Acoustic Emission method. To describe the plastic anisotropy, tension–compression asymmetry, pseudoelasticity and their evolution as a function of fatigue loading, strain-control experiments of varying amplitude were conducted in several steps. Experimental measurements at different stages of fatigue life revealed repeatable occurrences of twinning–detwinning, which is further shown to be coupled with reversible surface roughening. It was also found that although tension twinning contributes considerably to overall plasticity, it could also give rise to crack initiation towards the end of the fatigue life. The role of the reported microplasticity effects was additionally explored using a Continuum Dislocation Dynamics Viscoplastic Self-Consistent (CDD-VPSC) model for the first two cycles of the fatigue life. The intention of this section was to incorporate the effect of twinning–detwinning into the CDD-VPSC model and subsequently to capture the experimental effects associated with changes in the fatigue hysteresis observed between first and second cycle. These simulation results were consistent with the hypothesis that detwinning is responsible for the anomalous hardening behavior during the tensile part of the cyclic loading in the first few cycles of loading. This observation was confirmed for several imposed strain amplitudes and was achieved by properly defining an appropriate boundary condition that allows surface morphology changes. Furthermore, the experimental test plan allowed the quantification of the fatigue life in terms of hysteresis loop parameters including plastic/elastic energy, residual stiffness, as well as mean and extreme stresses. Finally, an energy-based relationship for the evaluation of fatigue behavior based on the Ellyin–Kujawski formulation was found to provide life predictions that agree with obtained experimental information”
