R&D Staff

Dr. Xiaohua Hu obtained his PHD degrees at State Key National Laboratory at University Science and Technology Beijing in 1998. Starting from 1999, he was a postdoctoral researcher at the Netherlands Institute for Metals Research (NIMR) located at Delft University of Technology where he developed a model to calculated interfacial adhesion energy of Zn coated steels. In 2001, he began to work as senior design engineer in Bovis Lendlease Microelectronics at Veldhoven, the Netherlands. He then moved to Belgium to work as a junior researcher at the department of materials and metallurgical engineering of The Catholieke Universiteit Leuven in Belgium from 2003 and worked on micromechanical modeling of work hardening behavior of pearlitic steels. He briefly worked as research associate at Case Western University at 2005 in thermal fatigue behavior of aluminum die casting dies and then moved to Canada to work as research associated at McMaster University where he worked on study the formability of automotive sheet aluminum alloys. From 2010, he was an CAE analyst at Litens Automotive Corp and work on finite element stress and fatigue analysis of automotive timing belt and accessory drive components such as tensioners, etc. He was then hired as research scientist at Pacific Northwest National Laboratory (PNNL) in 2012, where he developed the integrated modeling approach from sheet trimming to stretching and hole piercing to hole expansion of automotive aluminum sheet alloy and advanced high strength steels. He served as principal investigator of a couple of DOE-VTO projects on advanced high strength steels and Mg sheet alloy development. He started to work at Oak Ridge National Laboratory from 2018 and served as PIs for three high performance computing projects, collaborating with Pratt & Whitney, Ford Motor Company and Arcelor Mital Corp. He participated several DOE-VTO core programs such as joining, power train material and light metals programs. Due to his contributions to the development advanced high strength steels, he received the 2018 Institute Medal and 2019 Institute Medal Finalist awards from the American Iron and Steel Institute.
