West Lafayette, IN

• Constructed structure genome (SG) (smallest mathematical building block) for plate and beam analysis to overcome prevailing limitations of classical laminate plate theory (CLPT) and classical beam theory with use of.
• Homogenize SG for plate and beam model and apply to general case to determine resultant stress/strain and displacement of the structure, then de-homogenize the structures with determined strain and identify local damage
• Reduced considerable amount of computational cost compared to CLPT

West Lafayette, IN

• Investigated anisotropic and thermal properties of composite materials, tensile, compression, off-axis, flexural, thermal expansion coefficient, glass transition temperature, and Mode I and II interlaminar fracture.
• Used microscopic analysis to observe microstructure and estimate composition of fibers in the composite materials

• Connected local people to students and fundraised ($10,000/year) to open events for Korean community at Purdue university
• Connected current Korean students to alumni and helped alumni to open events in Korea

West Lafayette, IN

• Investigated the rheology, cure kinetics, and polymer transition by differential scanning calorimeter and dynamic mechanical analysis to measure viscosity, degree of cure, storage/loss modulus, and evolution of viscosity
• Characterized isothermal crystallization and glass transition temperature by investigation of heat transfer properties of carbon fiber reinforced polymers manufactured by various methods (VARTM/compression molding)
