Dr. Soondo Kweon joined ME faculty as an Assistant Professor in the Fall Semester of 2011. Dr. Kweon was born in South Korea. He graduated from the department of Mechanical Design and Production Engineering, Seoul National University with BS and MS in 1993, 1995 respectively. After graduation, he worked as an engineer at Hyundai-Kia Motors working on the design of underbody structures in Rio and minivans for 5 and a half years. After the first job, he worked as an engineering consultant at LG-CNS working on the improvement of the production lines at LG-Philips LCD and LG-Nikko Copper Inc for a little more than one year. Then, he worked at SEM (Samsung-Electro Mechanics) as an engineering project manager working on electric vibration motors that are used in cellular phones for 2 and a half years. He obtained two US patents out of the work at SEM and one of the patents earned him the 2nd best award for the best patents of the year from the Korean Government Patent Office in 2007.
He wanted to find a more enthusiastic and independent job than a company employee, so he decided to come to the US to study again after a 9 and a half year hiatus. He moved to Champaign, Illinois in 2004. Five years later in April 2009, he received a Ph. D. at the mechanical science engineering department, University of Illinois, Urbana-Champaign. The thesis topic is "Edge cracking in rolling of an aluminum alloy AA2024". He studied plasticity to solve the edge cracking problem. Through the study, he became knowledgeable in many areas of materials and mechanics including crystal plasticity (i.e., material characterization based on grain orientations (textures)) , damage mechanics, shear localization flow and J2 flow plasticity. He also became an expert in the finite element method (FEM). He developed 2D(axi-sym, plain strain) and 3D large strain finite element codes with material routines of crystal plasticity and J2 flow plasticity. He also coded QUS UMAT's(User Material subroutine) for crystal plasticity and J2 flow plasticity.
After completing his Ph.D., he worked at the aerospace engineering department, Texas A&M University for 2 years and 4 months. The research he performed there includes mechanical behavior of polymers using the macromolecular model, discreet dislocation dynamics simulation and mechanics of ductile fracture using an anisotropic constitutive model. He proposed corotational frameworks for the macromolecular model and anisotropic ductile fracture and implemented them into a 3D large strain finite element code and ABAQUS UMAT's.
He is an expert in experiments as well. During his Ph.D., he designed experiments and successfully performed them. The skills he obtained in that period includes the DIC (Digital Image Correlation) technique, specimen/jig design, specimen preparation (high resolution polishing) for microstructural work, i.e., microscopy and texture measurement and design of experimental procedures. He obtained the design/organizing skills for experiments from the nine and a half years of engineering experience in an automobile and an electric motor company, Hyundai-Kia motors, Samsung Electro-Mechanics, respectively, as an engineer. He obtained many patents including two US patents regarding vibration motors, which proves his capability as a great engineer and an experimentalist.
