Summary
Dr. Kim has published over 105 high-quality academic articles and technical papers. As a testament to his life's work, there are currently over 1,500 citations of his research. Dr. Kim is now known as a prolific writer and crowned with the above ORCID ID, which is connected to LinkedIn.com.
Kwang Yul Kim, PhD, has made pioneering contributions to the fields of physics and engineering. He established the thermodynamics of elastic solids at finite non-hydrostatic stresses, and in the field of physical acoustics, he made the first experimental observations of the focusing of fast and slow transverse waves in anisotropic solids. Other fundamental contributions include the derivation of group velocity formulas for anisotropic solids and, in materials science and mechanics, the derivation of nonlinear elastic equations of state. He has also designed and fabricated a high-frequency PVDF transducer, miniature PZT sensors, and high-fidelity displacement capacitive transducers, which are essential to understanding the characteristics of acoustic emission sources and various phenomena in geometrical acoustics. His most recent contribution to mechanical engineering is the design and construction of the Absolute Precision Load Gauge (APLG). The APLG provides advantages over conventional load cells by directly calculating the applied load in units of force or mass, thus precluding the need for its calibration. It is the very first invention of its kind.
