We are exploring the new application of DEM to fibrous composites (FCs). For FCs, the optimal discontinuous fiber architecture are not known, but can be proposed by advanced DEM computations which has the potential to advance the manufacturing of carbon fiber reinforced polymers, carbon nanotube polymer composites, and textiles.

Traian Dumitrica

Traian Dumitrica is a Professor of Mechanical Engineering at the University of Minnesota.  His major research interests are in the modeling and simulation of materials.  He uses DEM to develop computational technologies for guiding the development of composite fibrous materials. The focus is on materials for aerospace, where excellent mechanical properties and mass saving are key. He has authored or co-authored over 100 technical journal articles, and has received numerous awards, including the 2008 National Science Foundation CAREER and 2019-2020 Fulbright U.S. Scholar Awards.

Yuezhou Wang

Yuezhou Wang holds a Ph.D. in Materials Science from the University of Minnesota. Currently, he is an Assistant Professor at Minnesota State University, Mankato, where his research focuses on DEM simulations of large deformation mechanism in carbon nanotube yarns.

Hoa Xu

Hoa Xu holds a Ph.D. in Aerospace Engineering from the University of Minnesota. His research interest is in the development of multiscale simulations frameworks, where DEM is used for bridging atomic-level and macroscopic length scales. 

Grigorii Drozdov

Grigorii Drozdov is a Ph.D. candidate in Scientific Computation at the University of Minnesota. Grigorii has a Master degree in Computational Mathematics from Skoltech, Moscow and Bachelor degree in Mechanics from Novosibirsk State University. He is working on the development and implementation of mesoscopic DEM for the carbon nanotube composites.

Igor Ostanin

Igor Ostanin has received his Ph.D. in mechanics of materials from the University of Minnesota.
His thesis has established the possibility of DEM modeling of nanofibrillar materials. As an intern at Itasca Consulting group Minneapolis he contributed to the development of PFC code. As a Research Scientist at Skoltech, Russia and the University of Twente, Netherlands, he continues his work on few projects dealing with scalable and parallel computing, including massively parallel DEM simulations of fibrous materials and DEM modeling of acoustic metamaterials.
