Jianhai Zhang received his Ph.D. degree from School of Mechanical Engineering, Sungkyunkwan University in 2015. Currently, he is an associate professor in the School of Mechanical and Aerospace Engineering, Jilin University, China. His current research interests include New Technology of Mechanical Properties Testing in Extreme Conditions & In-situ Nondestructive Testing and Evaluation.

Nondestructive Evaluation in Jilin University

The Nondestructive Evaluation (NDE) thrust area at Jilin University (JLU) supports initiatives that advance inspection science and technology. Our goal is to provide cutting-edge technologies, that show promise for quantitative inspection and characterization of materials under the service process over the coming years. The NDE thrust area supports a multidisciplinary team, consisting of mechanical and electronics engineers, physicists, computer scientists, and technicians. These team members include personnel that cross departments within JLU, and some from academia and industry, within CHINA and abroad. To meet today's programmatic demands, it is important to increase collaboration among JLU engineering thrust areas and departments. This collaboration brings together the necessary and diverse disciplines to provide the key scientific and technological advancements required to meet JLU programmatic and industrial NDE challenges.

NDE provides materials characterization inspections of finished parts and complex objects, to find flaws and fabrication defects and to determine their physical and chemical characteristics. In addition, applying NDE throughout the life cycle of a part saves time and money and improves quality. NDE is being applied to new materials and to process design and development. NDE also encompasses process monitoring and control sensors and the monitoring of in-service damage. Therefore, NDE is becoming a front-line technology that strongly impacts issues of certification, life prediction, and life extension.

The primary contributions of the NDE thrust area in JLU are described in the five directions that follow: (1) New Techniques in Laser Ultrasonic Testing;(2) Advanced 3-D Imaging Technologies of PAUT;  (3) Infrared Thermal NDE of Materials or Structures; (4) Multi-magnetic  Nondestructive Evaluation; and (5) Multimodal NDE for In-service Components.
