Abstract:	Two different delamination mechanisms that need to be controlled by the drill geometry and thrust force will be observed in the drilling of composites. The studies which have been done up to now focus on the thrust force aspect and drill bit geometry at a constant feed rate. It is possible to find a feed rate at the beginning of the penetration that corresponds to the rate at which the laminates are peeled out. Moreover, at the exit, the fiber push-down mechanism is active, which can be controlled by controlling the maximum thrust force. Thrust force itself depends on the feed rate, so there should be a “feed ratedepth” graph minimizing the delamination. This implies that the feed rate may need to be changed from high to low as the drill bit enters and exits. To find the best result several experiments are being run at the constant feed rate. Some of these feed rates will give reduced fiber pull outs at the entrance and some will result in acceptable fiber push downs at the exit. The best graph will be extracted by analyzing the delamination for each feed rate. For measuring, a microscope should be used to determine the areas with the maximum delamination along the cross section of the hole. Also, measuring the surface roughness is another method of determining the delamination, but it should be done at a certain depth at the entrance as well as exit, not all of the thickness at once.

Abstract:	Space debris, are objects in Earth orbit consisting of small fragments from spent rocket stages and non-functional satellites. Accumulated in the lower earth orbit, these often cause considerable damage to the spacecraft orbiting around the earth. Hence it’s necessary to develop ways to protect the newly placed spacecraft from the debris. The goal of the project was to determine the damage area of the pressure wall using the Smoothed Particle Hydrodynamic (SPH) meshing, a dynamic finite element modeling (FEM) method.

Crevice corrosion theory, mechanisms and prevention methods

Abstract:	This paper reviews theory and mechanisms of crevice corrosion as well as its prevention methods. Crevice corrosion is one of the most important and harmful forms of localized corrosion that may cause sudden failure of the metal in service if not prevented properly. So far several protection methods against crevice corrosion have been developed including cathodic protection and using inhibitors and coatings. Hot wax dip method and sealing crevices with polysulfide are two popular protection methods currently used in automotive and aerospace industries respectively. However researches about this devastating type of corrosion still continue.
