Zou, Sheng (author), Xiao, Hanbin (author), Ye, Fangping (author), Li, Z. (author), Tang, Wenzhi (author), Zhu, Feng (author), Chen, Chentong (author), Zhu, Chao (author)The inevitably formed residual stress in the Selective Laser Melting (SLM) process leads to distortion, crack and even delamination of the workpiece. Single laser is commonly applied during SLM processing. However, its productivity is much lower than multiple lasers. In addition, the research of residual stress with multi-laser condition...journal article 2020

Li, Z. (author), Jiang, X. (author), Hopman, J. (author), Zhu, Ling (author), Liu, Zhiping (author)In this paper, we analyse the surface crack growth in the Fibre-Reinforced Polymer (FRP) reinforced steel plates subjected to tension by means of the finite element (FE) method. Following the experimental study, a three-dimensional FE model is developed to evaluate the Stress Intensity Factor (SIF) of the surface crack, and the crack growth...journal article 2020

Li, Z. (author), Jiang, X. (author), Hopman, J.J. (author), Zhu, Ling (author), Liu, Z. (author), Tang, Weiguo (author)Surface cracked steel plates reinforced with single-side Fiber-Reinforced Polymer (FRP) subjected to cyclic tension are experimental studied. The main purpose is to analyze the effect of FRP reinforcement on the crack growth. The failure modes and their effects are analyzed as well. Given the single-side reinforcement, reinforcing the cracked...journal article 2020

Li, Z. (author), Jiang, X. (author), Hopman, J.J. (author), Zhu, Ling (author), Liu, Zhiping (author)In this paper, we experimentally studied the external surface crack growth in steel pipes reinforced with Composite System Repaired (CRS). CRS reinforced surface cracked API 5L X65 pipes were tested, containing three initial notch sizes and four reinforcement schemes. During the tests, the crack growth results, as well as the strain on the...journal article 2020

Li, Z. (author), Jiang, X. (author), Hopman, J.J. (author), Zhu, Ling (author), Liu, Zhiping (author)In the present paper, we propose an analytical method to calculate the Stress Intensity Factor (SIF) of circumferential surface cracks in steel pipes subjected to bending. In light of pipe geometry and bending load case, the analytical formula is raised by introducing new bending correction factors and new geometry correction factors on the...journal article 2020

(author), Jiang, Yu-Long (author), Yu, Hongyu (author)In this paper, a method to extend the detection range of hydrogen sulfide (H<sub>2</sub>S) gas sensor is demonstrated. The sensor is based on AlGaN/GaN high electron mobility transistors (HEMTs) with Pt gate. It is observed that the as-fabricated devices exhibited sensing signal saturation at 30 ppm H<sub>2</sub>S exposure in dry air. A pre...journal article 2019

Liu, L. (author), Zlatanova, S. (author), Zhu, Q. (author), Li, K. (author)This paper introduces and compares two types of GML-based data standards for indoor location-based services, i.e., iIndoorGML and iIndoorLocationGML. By elaborating the advantages of the both standards and their data models, we conclude that the two data standards are complementary to each other. A jointed data model is presented to show the...conference paper 2017
