Dr. Gregory Szuladzinski, Ph.D., MSME
Dr. Szuladzinski received his Masters Degree in Mechanical Engineering from Warsaw University of Technology in 1965 and Doctoral Degree in Structural Mechanics from University of Southern California in 1973.
1966 to 1980: He worked in the United States mostly in the fields of aerospace and nuclear industries. The major employers were Northrop Corp. (structural design/analysis of Boeing 747 fuselage) Jet Propulsion Lab, Pasadena (Viking spaceship) Parker Hannifin (helicopter control mechanisms) and Aerojet General (nuclear plant structures and postulated accidents). There were a number of small projects taken up on consulting basis and relating to aerospace structures. He has done extensive work in computer simulation of seismic events and other dynamic conditions, as related to nuclear plant safety as well as military hardware.
1981 until present he has been working in Australia in the fields of aerospace, railway, power, offshore, and process industries. In aerospace the projects included an extensive analysis of A10 wing and landing gear, Mirage bomb rack structure including simulation of successive bomb ejection and response of Karinga bomb due to tail retarder. Also, automotive collisions were a subject of his computer simulations.
He has a number of publications to his credit in stress analysis, vibrations and nonlinear dynamics. His first book entitled Dynamics of Structures and Machinery, Problems and Solutions was published by John Wiley Interscience in 1982.
He has been involved with Finite Element Method of simulation of structural problems since 1966. In 1978-79 he worked as Principal Analyst for Control Data in Los Angeles in support of FEA codes, helping clients to formulate their analytical approach. He was instrumental in the effort to bring ANSYS code into Australia.
Since 1991 he has been doing research and computer simulations in the action of explosives, first in the area of rock breaking, then in the action of explosives on buildings and metallic structures. The analysis of violent phenomena included shock damage to buildings, structural collapse, fluid-structure interaction, blast protection and aircraft impact protection. He has done a number of state-of-the-art studies showing explicit fragmentation of structures and other objects.
His experience in transient nonlinear dynamics is summarized in his second book, Structural and Mechanical Shock and Impact Formulas (CRC Press, Oct.2009.) This has become an essential reference for many engineers who do related work.
In 2012 he began doing analysis of the Smolensk air crash of 2010 involving Tu-154M aircraft, studying various aspects of structural fragmentation caused by explosions and ground impact. Much of the related simulation work is available for public viewing.
He is a Fellow of the Institute of Engineers Australia, member of its Structural and Mechanical College, a member of the American Society of Mechanical Engineers and a member of the American Society of Civil Engineers.
