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......
