Effects of loading waveforms on rock damage using particle simulation method

Autor: Ming Xia, Feng-qiang Gong

Publikováno v: Journal of Central South University. 25:1755-1765

The particle simulation method is used to study the effects of loading waveforms (i.e. square, sinusoidal and triangle waveforms) on rock damage at mesoscopic scale. Then some influencing factors on rock damage at the mesoscopic scale, such as loadin

Effect of microstructure on impact resistance of chemical vapor deposited SiC coating on graphite substrate

Autor: Feng qiang Gong, Lin jing Wang, Haoran Wang, Zhao ke Chen, Xiang Xiong

Publikováno v: Surface and Coatings Technology. 380:125076

SiC coatings were prepared by chemical vapor deposition at 1050 °C, 1100 °C, 1150 °C, and 1200 °C by using methyltrichlorosilane (MTS, CH3SiCl3) as the precursor. The compositions, microstructures, and deposition kinetics of the coatings were stu

Cumulative Damage Monitoring of Shotcrete in Large-Span Tunnel under Multiple-Blastings

Autor: Feng Qiang Gong, Li Feng Li, Fang Ping Zhong

Publikováno v: Applied Mechanics and Materials. :1235-1238

In case of poor surrounding rock conditions, multiple-section blasting method is usually used in large-span tunnel. The sprayed concrete in tunnel will receive multiple blasting effects from different blasting section. Hence, its valuable to research

Probability Function Estimation of Rock Random Variables Using Chebyshev Orthogonal Polynomial

Autor: Feng Qiang Gong, Shang Qian Hou, Ting Yu Wu

Publikováno v: Applied Mechanics and Materials. :1673-1676

The Chebyshev orthogonal polynomial with sample moments (the origin moments) were used to approximate the probability density function (PDF) or cumulative distribution function (CDF) of variable (CPA method). Three examples from observed datas of uni
