Therefore, since the use of shell structures is for large applications, it is necessary to investigate the modification of the vibration characteristics of its design with the effect of nanomaterials and study the influence of other reinforced nanoparticle types on its features. Therefore, in this work, silicon nanoparticles were selected to investigate their effect on the vibration behavior of a shell structure. As a result, this work included studying the vibration behavior by testing the shell structure with a vibration test machine. In addition, after manufacturing the composite material shell with various silicon volume fractions, the mechanical properties were evaluated. In addition, the finite element technique with the Ansys program was used to assess and compare the vibration behavior of the shell structure using the numerical technique. The comparison of the results gave an acceptable percentage error not exceeding 10.93%. Finally, the results evaluated showed that the modification with silicon nanomaterials gave very good results since the nanomaterials improved about 65% of the shell's mechanical properties and vibration characteristics.","PeriodicalId":20137,"journal":{"name":"Physics and Chemistry of Solid State","volume":"161 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74506140","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}

An approach to estimate average density of electronic levels from which heterogeneous charge transfer takes place is proposed. An expression for obtaining a numerical value of cathode current density was established. Conditions of surface conductivity occurrence of a dielectric in a saline melt without its prior metallization are formulated. It is substantiated that the type of surface conductivity depends on reorganization energy, energy of reactants and reaction products in electrode field, transmission coefficient and other values which are determined by chemical composition of electrolyte, and can be calculated by analytical or quantum chemical methods. It was established that the adsorption of carbon dioxide on the surface of dielectric leads to a significant polarization of surface towards conduction band. The width of the band gap decreases, but the dielectric character of the cluster does not change, there is no band overlapping, i.e. an electrode does not acquire semiconducting and semimetallic character of conductivity. At the same time, adsorption of ВO2– on electrode surface leads to a strong polarization of the surface cluster towards the valence band, whlist a the band gap width decreases slightly, less than in the case of carbon dioxide.","PeriodicalId":20137,"journal":{"name":"Physics and Chemistry of Solid State","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79808604","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}
