Research interests

1. Nondestructive Evaluation and Structural Health Monitoring (NDE/SHM). The research interest includes using optical and acoustic technology to obtain the characteristics of materials, components and large-scale structures. Two main fields are focused on: A) model parameter identification and damage diagnosis for some large facilities or structures, for examples, offshore platform structures, pipelines, tanks, applying acoustic apparatus and modern signal processing methods. B) non-destructive evaluation of the characteristics and defects of composite materials using optoacoustic and optothermal methods, especially guided waves.

SAFE Modeling of a potential weld-guided wave mode: (a) vibration distribution in cross section (b) Mode shape in center of weld

One of the interesting researches now is the rapid NDE of long range butt welds in use of ultrasonic guided waves£¬to achieve this, we are using Semi-Analytical Finite Element (SAFE) models to predict wave motions in welds, as above figures show. Figure (a) tells one of the potential wave modes at the frequency of 100KHz in a butt weld of 10mm thick aluminum plate, the colors represent distribution of vibration in cross section, and the arrows indicate the displacements of particles. Figure (b) shows mode shape of this mode in center of weld, meaning axial displacement dominates the motion. Both numerical and experimental analyses are to predict the dispersion, velocity curves and cross-sectional mode shapes of the available weld-guided modes.

2. Application of CV in Precision Measurement. The calibration, the image processing, the 3D reconstruction are the focuses of this activity. Specific current research includes the development of new image processing algorithm and positioning during the micro-forming process for small precision mechanical components coupled with the control of positioning accuracy, the development of measurement of the miniaturized micro-scale tools and die/mould for the manufacture of components in the 10¨C100 ¦Ìm range.

Coding and Reconstruction by computer vision

3. Micro-forming and corresponding measurement. The research interest includes the mechanics and instability analysis of deformation processes in micro scale, material characterization and scale effects. The research has integrated experiment, analytical methods, control and sensors to initialize the adaptive method, measurement and apparatus for forming micro-parts, and to advance micro-forming processes and micro-manipulation.

Some modeling in laser aided micro-forming processes. (a) Modeling of the temperature field under laser scan (b) Modeling of average stress distribution during V-shape micro-bending
