Ying Luo

Dr. Luo specializes in welding, manufacturing, the mechanics of materials, and finite element analysis (FEA). She has expertise in the assessment of weld quality, weld metallurgy and grain structure analysis, and solid-state welding process development and optimization. She is also knowledgeable in manufacturing processes and system design, statistical process control, and product design using design for six sigma approach.

Prior to joining Exponent, Dr. Luo was a graduate student research assistant in Assembly and Manufacturing System Laboratory at University of Michigan, where she investigated ultrasonic welding of multi-layered aluminum and copper sheets. Specifically, the bonding mechanisms between similar and dissimilar materials and joint propagation between interfaces. Through this work she demonstrated that interdiffusion and dynamic recrystallization are the key bonding mechanisms of joint formation in a uni-directional manner in the studied conditions. She also predicted bonding strength of the welds by mechanical tests, metallurgical examinations of the weld macrostructure and microstructure, and finite element modeling using Abaqus. In addition, Dr. Luo developed a localized preheating method to enhance the weldability of multi-layered copper sheets and analyzed the thermo-mechanical behavior using finite element modeling.
