معرفی
Dr. Chien-Cheng Hung is a Researcher in the Department of Earth Sciences within the Faculty of Geosciences at Utrecht University, specializing in experimental rock deformation and fault mechanics.
His primary research focuses on understanding the micromechanics of small magnitude earthquake slip through his project "probing the micromechanics of small magnitude earthquake slip" (also known as "how hot do faults get"), conducted within the DEEPNL research program. Dr. Hung combines friction experiments with numerical discrete element method (DEM) to explore strain localization in fault gouges and the effect of multi-phase fluids on heat generation at grain contacts.
His experimental methodology includes direct shear experiments using triaxial vessels at low slip velocities (nm/s to mm/s) and slip-pulse experiments with rotary-shear apparatus at high slip velocities (up to m/s). This work aims to determine temperature rise and weakening during small slip events, particularly for induced seismicities in the Groningen area, contributing to understanding friction breakdown processes that control maximum earthquake slip and magnitude.
Dr. Hung's technical expertise includes:
- Rock Deformation
- Scanning Electron Microscopy (SEM)
- Raman Spectroscopy
- Transmission Electron Microscopy (TEM)
