Research slope stability under rainfall condition in geotechnical centrifuge is an ideal test method, however, the influence of high centrifugal force field produced by running geotechnical centrifuge cannot be neglected. Droplet deformation and breakup under different gravity and of different diameters were studied with VOF method, the results shows that the process of droplet deformation and breakup is similar under condition of different g-value and diameters, droplet breakup in a very short time in high gravity field, and with the increase of g-value, the breakup time of droplet became shorter, with the increase of droplet diameter, the breakup time of droplet became longer under same gravity acceleration. Studies in this paper have important significance in developing geotechnical centrifuge artificial rainfall equipment.

By taking combustion synthesis in high-gravity field to achieve fusion bonding of TiB2-based ceramic, Ti-6Al-4V alloy, the mid-ceramic and 42CrMo steel simultaneously, the ceramic-metal FG multilayer composites with the continuously-graded interfacial microstructures were successfully fabricated. XRD, FESEM and EDS results showed the formation of continuously-graded interfacial microstructures among TiB2-based ceramic, Ti-6Al-4V alloy, the mid-ceramic and 42CrMo steel resulted from thermal explosion reaction caused by high gravity field, liquid fusion of the ceramic, Ti-6Al-4V alloy, the mid-ceramic and 42CrMo steel, so hard-by-soft distribution in the hardness of FG multilayer composite was presented, and the interfacial shear strength of TiB2-based ceramic and Ti-6Al-4V alloy, and the mid-ceramic and 42CrMo steel measured 198 ± 25 MPa and 130 ± 15 MPa, respectively.
