J. Cent. South Univ. (2018) 25: 2537-2549 DOI: https://doi.org/10.1007/s11771-018-3934-1 Elasticity solution of laminated beams with temperature-dependent material properties under a combination... Abstract: An exact solution for simply-supported laminated beams with material properties variable with temperature under a combination of uniform thermo-load and mechanical loads was investigated......
materials were studied using the pin-on-disc method. The friction coefficient of Ti3SiC2-based material was not very sensitive to normal load, the steady state value, μ, increased from 0.4 to 0.5... material was 9.9×10-5 mm3/Nm. The debris on the Ti3SiC2 disc was essentially made up of Ti3SiC2 and steel pin materials, while the debris on the steel sliders was generally pin material. The wear mechanism......
Photon-Ion Catalysis Synergy Material and Its Application金宗哲,王毅,王圣威,黄丽容摘 要:<正>The co-operation action mechanism and model of photon-ion catalysis synergy material composed of thallium and valency-variable rare earth elements and semiconductor oxide were proposed. The radiation catalysis reactions of water and oxygen assisted by the synergy......
