Pricipal Engineer
Applied Reseach Associates
Panama City, FL, United States
Dr. Hyung S. Lee is currently a Principal Research Engineer with the Aircraft Operating Surfaces (AOS) Group of Applied Research Associates. He is a Civil Engineer with a Ph.D. degree in Pavement & Materials Engineering from Michigan State University.
Dr. Lee joined ARA in 2006 as a staff engineer and worked as a full-time consultant engineer for the Florida Department of Transportation (FDOT), managing ARA's nondestructive testing activities for FDOT. In 2010, he joined FDOT as the State's Nondestructive Testing Engineer prior to rejoining ARA in 2015. Dr. Lee has 20 years of experience in the field of pavement evaluation, structural analysis, and forensic investigations using nondestructive testing devices such as falling weight deflectometer (FWD), ground penetrating radar (GPR), locked wheel friction testers, and various texture meters. In addition, Dr. Lee has conducted various research studies on vehicle–pavement interaction, dynamic modeling of asphalt and concrete pavements, pavement surface characteristics as well as viscoelastic asphalt material characterization.
Dr. Lee is the original developer of ViscoWave: a dynamic Finite Layer Method (FLM) which is capable of modeling the dynamics (i.e., transient stress wave propagation) of a variety of flexible pavement structures with elastic/viscoelastic layers, with/without bedrock. ViscoWave has been released as an open-source code at (https://github.com/leehyu20/ViscoWave). He is also the original developer of DSteele (Currently under development) which is a 3D spectral element solution for flexible pavement response under moving aircraft and vehicle loads.
