Повний текст джерелаThis Ph.D dissertation aimed at the comprehensive understanding and the constitutive modeling of the mechanical behaviours of the surface mechanical attrition treatment (SMAT) treated AISI304 stainless steel sheet under a large range of loading rates. SMAT treated AISI304 stainless steel sheets are multi-layered functionally graded materials (FGM). The main research results and conclusions are summarized as followed:(1) The overall rate sensitivity SMAT treated AISI304 stainless steel sheet is characterized by the double shearing test under quasi-static and dynamic loading where a large strain can be achieved without geometry instability. Impact double shear test are performed with a large diameter Hopkinson bar system and an adapted equal-impedance clamping device. Significant rate sensitivity is found. It is also observed that such a rate enhancement does not induce an important reduction of the ductility.(2) In order to extract accurate material information from the double shear tests, their testing conditions are thoroughly analyzed using numerical simulation. Numerical models including clamping devices have been built to investigate the influence of this clamping device at the early stage of loading. A limited effect was found for various imperfect testing conditions such as the clamping device stiffness, non-homogeneous stress and strain fields, non-equilibrium state, etc. On the contrary, numerical and analytical study shows that the simple small strain assumption usually used in double shear tests are not accurate enough. Eulerian cumulated strain definition should be used to get consistent numerical results. From this finding, the experimental rate sensitivity obtained for the SMAT treated AISI304 stainless steel sheet are recalculated.(3) A multi-layers elastic plastic damageable constitutive model is proposed to model SMAT treated AISI304 stainless steel sheet. The parameters are identified using tensile testing results. The elastic plastic behavior is curve fitted with a simple Ludwig hardening model. However, the damage parameters should be identified using an inverse method on the basis of numerical simulation of these tensile tests. In order to validate this multi-layer elastic plastic damageable constitutive model, indentation/piercing tests on SMAT treated AISI304 stainless steel sheet are performed. Numerical simulation of this indentation/piercing tests is also realized. It is found that the identified multi-layer elastic plastic damageable constitutive model allows for a quite accurate prediction of the experimental piercing tests.(4) In order to evaluate the impact anti-piercing capacity of the SMAT treated AISI304 stainless steel sheet, the impact perforation tests using Hopkinson bar are carried out. Numerical simulation of these impact perforation tests are realized with a similar FEM model as the quasi-static case. As the rate sensitivity of SMAT treated AISI304 stainless steel sheet is experimentally characterized with double shear test, a rate sensitive multi-layer elastic plastic damageable constitutive model is introduced. The numerical results agree well with the experimental ones, which indicates the effectiveness of the numerical model as well as the rate sensitive multi-layer elastic plastic damageable constitutive model

A study of fixing plastics to an aluminum-magnesium alloy 5052. First, the aluminum-magnesium alloy 5052 was surface-treated via electropolishing reaction. While the surface roughness of the aluminum-magnesium alloy 5052 was 16.3 mm before electropolishing, the roughness of the electropolished surface was 3.1 nm. We find that the surface morphology was uniform. The aluminum-magnesium alloy 5052 was further surface-treated via anodic treatment. After that, we observed self-organized formation of nanopores arrays in aluminum-magnesium alloy 5052, and the diameters of nanopores were measured 31.8 ± 3.6 nm. The connection between surface-treated aluminum-magnesium alloy 5052 and polyphenylene sulfide (PPS) was via injection molding. The mechanical properties of bonding plastic on aluminum-magnesium alloy 5052 were studied through both normal tension test and horizontal strength test. The testing result of normal tension test and horizontal strength test are respectively 95.7 ± 3.2 nm and 389.8 ± 7.4 nm. And in order to ensure the practical application in environmental temperature and humidity, the environment test of bonding plastic on aluminum-magnesium alloy 5052 was operated in the temperature between -10 ℃ ~ 70 ℃ and relative humidity remained at 75%. The result shows a slightly reduction mechanical properties after the environmental test.

The application of plastic substrates in optical components increased recently. The limitation in using plastic substrates for optical components was the poor adherence between thin films and substrates. This research focused on plasma surface treatment to enhance the adhesion. The change of surface roughness, chemical bonding, substrate transmittance with different gas and pre-treatment power was investigated. In addition, we coated Ta2O5 single layer on substrates after pre-treatment to find out the phenomenon of the inhomogeneity as well as the adhesion degree between Ta2O5 and plastic substrate. The results revealed that the improvement of adhesion related to plasma power and pre-treatment time. It took shorter time to reach good adhesion under high plasma power, while longer time under low plasma power. But, high power plasma treatment caused substrate overheated due to the volatile interaction between plasma and substrates. So we chose low power treatment with longer time as well as cathode cooling. Finally, it is found that by refining the design of anti-reflection coating with an interface layer, an anti-reflection coating on plastic substrates with good adhesion can be made.
