Analysis of the Crack Evolution Process in Crumb Rubber Concrete Based on Acoustic Emission Technology

Pan Ming,Jun Lu,Xin Cai,Miaoyan Liu,Xudong Chen 대한토목학회 2020 KSCE JOURNAL OF CIVIL ENGINEERING Vol.24 No.7

In this study, the crack evolution process of crumb rubber concrete (CRC) in a four-point bending tensile test was monitored using the acoustic emission (AE) technique. The peak frequency, distribution characteristics of the AE source, and the damage process based on the AE ring count during the crack evolution were analyzed. The test results revealed that the addition of rubber particles decreased the brittleness of cracks and improved the ductility of the concrete during the macro-cracking process. The AE positioning method could effectively monitor the evolution process of micro-cracks inside the concrete. Additionally, based on the statistical results of the AE source events and energy distribution, the position of macroscopic cracks could be predicted, and the random distribution of micro-cracks could be characterized. By introducing the Weibull distribution to describe the random growth process of micro-cracks, the damage inside the concrete could be qualitatively predicted. As the rubber particle content increased, the inherent micro-cracks inside the concrete also increased. The damage inside the concrete was biased toward the crack nucleation stage.

The Clamping Position Optimization and Deformation Analysis for an Antenna Thin Wall Parts Assembly with ASA, MIGA and PSO Algorithm

Ming-hui Pan,Wen-cheng Tang,Yan Xing,Jun Ni 한국정밀공학회 2017 International Journal of Precision Engineering and Vol.18 No.3

In order to reduce the deformation and assembly error in an antenna thin wall parts assembly process, the assembly location or clamping positions need to be optimized. In this paper, the effect of clamping positions and clamping force on the thin wall parts deformation is analyzed considering the gravity by finite element simulation under different clamping force. The clamping positions are optimized with the Adaptive Simulated Annealing (ASA), Multi-Island Genetic Algorithm (MIGA) and Particle Swarm Optimization (PSO) algorithm by Isight software to reduce the deformation. Comparing with MIGA and PSO method, the results show that the clamping position optimization based on ASA exhibits the better results and superior than the MIGA and PSO no matter whether it has the effect of gravity. Simultaneously, through establishing the contact force model and contact deformation model, the nonlinear relationship between contact force, contact deformation and contact area is qualitatively analyzed, and the node deformation is calculated by theoretical formula. Comparing with those results, it is shown that the theoretical value matches well with the simulation results. Finally, some clamping scheme principles are proposed so that it provides a basis for reducing the deformation and assembly error of thin wall parts in future.

Ng Pan Pan,Chow Boris Chun Kei,Cheung Stephen Chi Wai,Ng Ming-Yen 아시아심장혈관영상의학회 2022 Cardiovascular Imaging Asia Vol.6 No.1

Coronary artery anomalies are uncommon with variable clinical significance. We present a case of 49-year-old gentleman with atypical chest pain, who was found to have single left coronary artery, anomalous right coronary artery with pre-pulmonic course, as well as coronary- cameral fistula on coronary computed tomography angiogram (CCTA). CCTA demonstrated no significant coronary artery stenosis to suggest ischemic heart disease nor ventricular dysfunction to suggest significant hemodynamic consequence secondary to the coronary anomalies.

Splenic T1-Mapping for Predicting Adenosine Stress Adequacy in Cardiac Magnetic Resonance Myocardial Perfusion Imaging: A Validation and Reproducibility Study

Wan Fiona Fong-ying,Yeung Catherine Ming-mun,Yam Pak-ki,Ng Pan Pan,Chow Boris Chun Kei,Chiang Jeanie Betsy,Lee Jonan Chun-yin,Cheung Kenneth Kai-yat,Ng Ming-yen 아시아심장혈관영상의학회 2022 Cardiovascular Imaging Asia Vol.6 No.3

Objective:Splenic switch-off (SSO) sign has been utilized as a surrogate marker of adequate stress but can only be assessed after first-pass perfusion imaging. A study previously reported that drop in T1spleen ≥30 ms during adenosine infusion predicts presence of SSO, but this finding has not been externally validated. This study aimed to prospectively validate whether drop in T1spleen ≥30 ms is a reliable marker of SSO and hence adequate stress, and to assess reproducibility of T1spleen measurements. Materials and Methods: Data of fifty consecutive patients undergoing stress cardiac magnetic resonance were prospectively collected. Native T1-maps were acquired at rest and at 2.5 min after adenosine infusion in short axis slices, followed by perfusion images at 3 min. To measure T1spleen pre- and post-adenosine infusion, regions of interest were manually placed to include most splenic tissue. Adenosine stress adequacy was evaluated by visual SSO assessment and semi-quantitative splenic perfusion analysis. Results:A significant association was found between a drop in T1spleen of ≥30 ms and SSO response (p<0.001). There was excellent correlation between SSO response and semiquantitative perfusion change in spleen (rho=0.847, p<0.001). Inter-observer and intra-observer agreement for measurement of ΔT1spleen values were excellent, with intra-class correlation coefficients of 0.987 and 0.995, respectively. By receiver-operating characteristic analysis, the optimal cut-off value of ΔT1spleen for predicting presence of SSO was -28 ms, with area under the curve=0.76 (p=0.002). Conclusion:Splenic T1-mapping is accurate and reproducible for predicting SSO, potentially allowing optimization of adenosine dosage for adequate stress.

Study on the Influence of the Initial Deflection and Load Combination on the Collapse Behaviour of Continuous Stiffened Panels

Ming Cai Xu,Zhao Jun Song,Jin Pan,C. Guedes Soares 한국강구조학회 2017 International Journal of Steel Structures Vol.17 No.4

Using the finite element analysis, a series stiffened panels under combined normal loads and biaxial compressions are conducted to investigate the effect of several influential factors on the ultimate limit states. Two spans/bays FE model with periodical boundary condition is adopted to consider the interaction between adjacent structural members. The initial deflections assumed as Fourier components including symmetric and asymmetric modes are used to identify the half-wave number of collapse of the local plate, which is compared with half-wave number of buckling calculated by formula. Based on the numerical results, the influences of half-wave number assumed in the equivalent initial imperfection and loads combination on the collapse behaviours of stiffened panels are discussed. It is found that lateral pressure might increase the ultimate strength of stiffened panels for the stiffener-induced failure modes. The one half-wave region of local plate influences significantly the load carrying capacity of stiffened panels.
