Dr. Bart F. Zalewski is a structural analysis lead at L3Harris Technologies, inventor, martial artist, and a former technical fellow and analytical division supervisor at ZIN Technologies, Inc (ZIN), NASA contractor, professor, entrepreneur, and amateur fighter. He has received a B.S. and M.S. degrees under Professor Arthur A. Huckelbridge with a focus in structural engineering in May 2005 from Case Western Reserve University (CWRU). His M.S. thesis dealt with dynamic load effects on bridge-mounted structures. He received his Ph.D. from Case Western Reserve University in August 2008 with a focus in computational mechanics under Professor Robert L. Mullen. His Ph.D. dissertation dealt with discretization errors in Boundary Element Method (BEM). He is also an alumnus of the Center for Reliable Engineering Computing (REC) and a member of the Quality and Robust Design Committee of SAE. From 2010 to 2013 he served as an Adjunct Assistant Professor at the Department of Civil and Environmental Engineering at CWRU. From 2013 to 2018 he was a chief engineer in a company he co-founded, ZalNear Space, LLC, to develop new technologies for near space flights. From 2008 to 2021 he worked at ZIN developing launch vehicle technologies in four different engineering areas: structures, dynamics, acoustics, and additive manufacturing. In 2017, he won a prestigious NASA Trailblazer Award for developing the fastest vacuum stage separation software in the world, by orders of magnitude, enabling NASA to conduct extensive payload Fairing Separation trade studies.
About Me:
I was born in Gdynia and spent my first four years growing up in Sopot, a Baltic seaside resort city known for its beauty and charm. At the age of four, I moved to the neighboring city of Gdansk, the birthplace of Solidarnosc movement, which is rich in history, various forms of architecture, and home to some of the record holding structures such as Bazylika Mariacka and Zuraw. At the age of twelve, I moved to Cleveland, which is Gdansk’s sister city, a beautiful city on the shore of Lake Erie that is known as the Comeback City. Following my father's footsteps, I studied structural engineering and worked on design and development of the next generation NASA heavy lift vehicle. At the age of forty, I moved to Dallas near the shore of Lake Ray Hubbard and Sapphire Bay, which as part of the large Metroplex is the fastest growing and one of the most powerful economies in the country and the world. I've been practicing martial arts for over twenty years including: Catch Wrestling (Hooker), Folkstyle Wrestling (Varsity), Shotokan Karate (Purple Belt), Muay Thai (Green-White Mongkol), Jujutsu (Green Belt), Goshin Jutsu Karate (Green Belt), Gracie Jiu Jitsu (White Belt - 3 years), Tai Chi (Level 1), and Cleveland Catch Wrestling (Black Shirt). I also have some training/exposure in Greco-Roman Wrestling, Jeet Kune Do, Taekwondo, Rooster Style Kung Fu, Knife Fighting, Machete Fighting, and Boxing. I am a 2016 NAGA Ohio Light Heavyweight Grappling Champion, ranked by International Submission Only Federation as a Black Belt, and was nationally ranked as top 35% no-gi grappler. My great-great-grandfather, Adam Carl Kupperschmitt, was a famous Sopot architect; my great-granduncle, Commander Wladyslaw Salamon, was a commander of ORP Sep during WWII; my uncle, High Chief Dr. Raymond Dokpesi, is a media businessman; and my grandfather, Edmund Steinke, was an amateur Bantamweight boxer and a WWII veteran. My great-grandfather, Jan Steinke, was a Gdansk crystal businessman and founder of a Polish school in Gdansk Nowy Port. He was imprisoned, tortured, and killed by the Polish government in 1947.
Interests:
Dr. Zalewski’s interests include Computational Mechanics, Finite Element Methods (FEM), Boundary Element Methods (BEM), Mesh Free Methods (MFM), Finite Difference Methods (FDM), Composite Structures, Near Space Technology, Acoustic Attenuation Techniques, Separation Analysis, Interval Analysis, Fuzzy Analysis, and Reliable Numerical Methods. He developed the first method to provide guaranteed bounds on the real discretization errors, not on the estimates, using a set weak form, or possibilistic weak form. He is also one of the pioneers of the interval boundary element method (IBEM) and fuzzy boundary element method (FBEM). Dr. Zalewski developed interval kernel splitting technique (IKST), which encloses the true solution to Fredholm equations of the first and second kind. He has received numerous awards for research and technology development and was featured in NASA magazines. Dr. Zalewski is an author of several peer reviewed journals and conference publications and has an h-index of 8, appropriate for an associate professor. He researched techniques for solving improper interval linear system of equations and providing exact bounds for the inner enclosure in a weak sense. He also researched the usage of improper intervals for providing inner bounds on the local discretization error for boundary element methods. Other research topics include material uncertainty in boundary element method, local discretization error enclosure for finite element method, and local discretization error for a residual interval boundary element method (RIBEM). As part of ZalNear Space, Dr. Zalewski researched and developed new technologies for near space vehicle. He performed structural design/analysis, mechanical design, and trajectory analysis, as well as schedule, cost, and requirement development. He invented, co-developed, and successfully tested the Passive Parachute Deployment System (PPDS).
At ZIN, Dr. Zalewski worked on NASA's Space Launch System (SLS) project which will allow for deep space exploration. His work included composite structural analysis and optimization of the Payload Fairing, its separation, and acoustic attenuation. He invented Stitched Bonded Joint (SBJ) for cured composite panels, Reconfigurable Structural Joint, Deployable Structural Joint, Tuned Chamber Core (TCC) acoustic treatment, Chamber Attenuator for Low Frequencies (CALF), Equidistant Chamber Attenuator for Low Frequencies (eCALF), Layered Equidistant Chamber Attenuator for Low Frequencies (LeCALF), Wedge Equidistant Chamber Attenuator for Low Frequencies (WeCALF), and Optimized Additive Manufacturing Process. He also developed SepTool©, a software for evaluating separation clearance that combines fairing flexible dynamics with rigid body dynamics of the vehicle. SepTool was used by NASA to analyze SLS Block 1 and Block 1B Payload Fairing and SLS Universal Stage Adapter separation clearance and Vector-H Payload Fairing separation clearance.
Currently, Dr. Zalewski is working on stress analysis for aircraft structures at L3 Harris creating a safer world and more secure future.
Bart has been in more than 450 fights including: competitions, back yard fights, and street fights with one or multiple opponents. Based on his study of various martial arts and fighting experience, he developed Cleveland Catch Wrestling, which is a mixed fighting style heavily leveraging Catch Wresting and is currently teaching the art. Cleveland Catch Wrestling focuses on practical, efficient, and brutal methods for self-defense and therefore includes: strikes both stand up and on the ground, clinching, takedowns, rides, rips, strangles, locks, hooks, and chains. Bart innovated Cleveland Calflock submission hold, which is a modified Ashi Zaru Leglock, targetting BL-57 and BL-58 pressure points.
