This paper reports the modeling of MEMS based Piezoelectric shear actuated beam by using COMSOL Multiphysics software of version 4.2a.The dimensions of the model beam is of 100-mm long, 30-mm width, 10-mm thickness. In this paper, we analysed the deflection of beam under different voltages. In the first step, deflection of beam is analysed by changing the material of sandwiched beam. In the second step deflection of beam is explored by changing material of electrodes. In the third step, deflection of beam is analysed by changing both materials of sandwiched beam and electrodes. In the final step defection of beam is explored by changing both thickness and material of electrodes. Finally, the results of analysis allowed to conclude us to design a piezo electric shear actuated beam with different ranges and resolutions, under the condition of changing both thickness and material of electrodes gives the optimum deflection of 216nm under 30v excited input voltage.","PeriodicalId":7420,"journal":{"name":"American Journal of Materials Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75995467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The energetic state of the in itial mixture was established to be a determin ing factor which affects the principal features of solid state interaction whereas an increase in dispersity only influences the temperature of the interaction start. When non-activated initial mixtures and ones mechanically activated in a p lanetary mill with lo w number of dru m revolutions were used, the solid solution formation proceeded owing to diffusion of silicon into metals through successive formation of lo wer and higher molybdenum-based silicide phases followed by their interaction. Mechanical activation in a planetary mill with high number of dru m revolutions was accompanied by not only decrease in particle size but also changes in the energetic state of the reaction mixture, which resulted in changing the regularities of the solid solution formation. Herein solid solutions on the basis of two higher molybdenum silicide phases, tetra- and hexagonal mod ifications, were formed with further poly morphic transition of the unstable high temperature hexagonal β-MoSi2 phase into the lo w temperature tetragonal α-MoSi2 phase. It has been established that temperature of the beginning of interaction decreases by 100℃ as compared with non-activated initial mixtures and temperature of the end of the process depends on the amount of accu mu lated energy: under low energy mechanical activation the process is co mplete at 1200℃, while a h igh energy activation decreases this temperature by 200-400℃ depending on the duration of activation.","PeriodicalId":7420,"journal":{"name":"American Journal of Materials Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87928018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
