With the reduction in size and weight for electronic products, particularly for accurate manufactures, the IC boards used to achieve complex circuit functions become smaller and lighter. It is also needed to make the board thin. The layers stacking assembly together will be more important, but the precision requirements of the device can not be reduced, either. The purpose of the stacked vertical...
In this paper the effect of the accessory in notch in bow on ship resistance performance is studied based on computational fluid dynamics (CFD) calculation in respect to a self-propelled cutter suction dredger. This research finds the ship resistance performance of the ship with notch in bow changes a lot because of the accessory in notch in bow. And there is a critical angle between the accessory...
Firstly, the technical principle of Y-section pile and mechanism on central diaphragm setting of Y-section sinking pipe were introduced. In the process of driving of Y-section sinking pipe, concrete pouring and uplifting of Y-section sinking pipe, the Y-section sinking pipe is subjected to alternate cycle load of compression-expansion-recompression, the significant deformation and even failure occur...
The section shape of piles becomes various along with the development of piles. The additional stress in the ground due to skin friction and tip resistance of pile is different in different section shape. Using the numerical integral function of NIntegrate in Mathematica software, basing on Mindlin stress solution and referencing the idea from Geddes stress solution; The calculation method on additional...
Basing on Mindlin stress solution, referencing the idea from Geddes stress solution and using the numerical integral function of NIntegrate in Mathematica software, the numerical computational methods for vertical additional stress coefficient at random point in the ground under the uniform tip load of the rigid pile with circular tip and the flexible pile with annular tip were achieved. A numerical...
