The laboratory is conducting the research on the relationship between the macroscopic mechanical behaviors and the microscopic structures of advanced engineering materials based on micro-mechanical approaches. In addition to the mechanical testings such as tensile and fatigue tests, the microstructural examination by electron microscopes and the nondestructive evaluation (NDE) by elastic and electromagnetic waves are utilized. A special emphasis on acoustic emission (AE) is due to the fact that AE being generated by mechanical disturbance in solids at microscopic level, it can be utilized for the range of applications from the characterization of material to the diagnosis of machineries during operation.
Fields of research interest
1. Aerospace Grade Composite, Fatigue Damage of CFRP-Metal Joint, Impact Damage Assessment of Curved Composite Laminates
2. Damage diagnosis by AE and Surface Acoustic Wave (SAW), Location of Short Fatigue Cracks and Their Growth, Fatigue Life Estimation
3. New Sensing Techniques for Noncontact NDE; Fiber-Optic Interferometer and Intensity-Based Optical Sensors, Improved SNR by Wavelet Transform.
4. Monitoring of Laser Materials Processing; Laser Cladding and Rapid Prototyping, Noncontact and Noninvasive Measurement for In-Process Diagnosis
