In order to overcome the disadvantages of the traditional Fourier Transform, a wavelet de-noising algorithm of chaotic signal is used. The basic principle of wavelet de-noising is introduced in detail. Using Chebyshev chaotic sequence as source signal, the performance of different parameters wavelet for noise reduction was analyzed. The simulation results show that the proposed algorithm is practicable and effective.

Research on Fracture Behavior of Film-substrate System

Research on Fracture Behavior of Film-substrate System

第一届工程科学与力学中的计算方法国际会议

作者： Baoliang Liu and Xianshun Bi Department of Mathematics and Mechanics Heilongjiang Institute of Science and Technology harbin 150027 China

＜正＞The last decade has seen enormous progress in the area of integrated circuits, microelectronic, and micro-machined devices. These engineering systems typically consist of dissimilar materials joined together on a substrate, i.e. the film-substrate composite system. Owing to the high performance demands of engineering devices, film technology profoundly affects the lifetime of materials. In filming process, the thermal stress exists due to the difference among the thermal expansion coefficients of the film and the substrate, which may result in cracking of the films. Thus, the reliability of these systems often depends on the fracture behavior of the films comprising the device and a good understanding of the possible failure mechanisms makes it possible to design more reliable devices. This study gives the problem of a crack in the film oriented perpendicular to the film-substrate interface with the crack tip fully within the film. Based on Beuth’s theory, three-dimensional model is simplified to plane strain problems, which obtains fracture mechanisms of a cracked film-substrate system by applying the boundary element method（BEM）. The method aptly resolves the problem involving stress concentration The results indicate: the stress intensity factor is affected by the different elastic mismatches and the thickness ratio of the film and the substrate, and it has remarkable increased with the decrease of the thickness ratio of the film and the substrate. The effect of the fracture behavior of film is negligible when the thickness ratio of the film and the substrate is more than 10. The conclusion has theoretical significance for researching fracture behavior of film-substrate system by experimental mental method. What’s more, this paper studies the special condition of the film-substrate system, which is the analysis of the fracture of the absence of any elastic mismatch between the film and the substrate, i.e. α=β=0, and revision of the formula of Xia and Hutchinso

＜正＞This paper calculates and analyzes the simplified mechanical model of flat trapezium teeth connector by using finite element analysis soft （ANSYS） and comes at detailed stress distribution on the teeth joint. Dynamic fatigue experiment is made accordingly on the most typical flat connector in flight conveyor now being used in coal mine. By analyzing the process of fatigue fracture of test sample, the authors get the detailed evolutionary process of producing fatigue cracks and come to know that the connector needs the cycle index of 18000 or so to produce the fatigue cracks. This result provides the basis of the theory and experiment for the reasonable designing of the flat connector and the prolonging of its fatigue life.
