Nano Mechanics Micro Reliability Lab

Welcome to NMMRL !

My name is Jong-hyoung Kim. I am an assistant professor at Pukyong National University, Department of Materials Science and Engineering.
Our lab is Nano Mechanics & Micro Reliability Lab and our research interests are as follows:

Before joining Pukyong National University, I was a Postdoctoral fellow at the Harvard SEAS working with Professor Joost Vlassak, since Sept 2019. I studied the following research related to mechanics and material science. My research covers studies related to mechanics in the entire life cycle of materials, from material design through fabrication, characterization, and modeling to reliability. 

• Mechanical behavior of 2D nanolattice structure, and its applications as a photophoretic levitation device

• Fracture of polymers in aqueous corrosive environment, and their effects on structural reliability

• Mechanical characterization of materials in multi-scales using machine learning: how to reduce the Sim-to-Real gap

During my PhD, I did research under the guidance of Professor Dongil Kwon in the Department of Materials Science and Engineering at Seoul National University. I mainly studied instrumented indentation technique to evaluate the mechanical properties of materials. My dissertation is about evaluating the surface residual stresses of material by using indentation technique and digital image correlation method, and a method of evaluating the structural integrity of a component based on fracture mechanics considering the residual stress. 

I have many experiences in mechanical testing, nano/micro-fabrication, and finite element analysis. If you are interested in my research or want to discuss with me, please contact me! (Email: jhkim@pknu.ac.kr  kjh2677@snu.ac.kr)
