In this work the analytic solution of a plane problem (plane strain and plane stress) for bi-material plate with an elliptic hole is obtained. A hole is located entirely in a lower half-plane. The constant stresses are given at infinity and on the boundary of the hole an external load is applied. The methods of Kolosov–Muskhelishvili complex potentials, conformal mapping and superposition are used for the solution of the problem. The affinity of a hole to an interface makes essential influence on value of stresses in a vicinity of a hole and on value of stresses at an interface. For engineering applications it is important to know the fields of the stresses and displacements in order to estimate influence of a hole on strength of structure. From considered problems as special cases follow the solutions of problems about a half-plane with an elliptic hole, about an inclined crack in a bi-material plane and half-plane.","PeriodicalId":407958,"journal":{"name":"2016 Young Researchers in Vacuum Micro/Nano Electronics (VMNE-YR)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124479018","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}

Numerical modeling of the field emission current with a normally distributed noise is carried out. Based on the method of least squares, estimates of the parameters of the Fowler—Nordheim equation are constructed. The application of statistical tests showed that in most cases the remains of a linear regression model are normally distributed, in spite of the logarithmic transformation of the integrated current-voltage characteristics. In a sense, the results are justify the applicability of the convenient methods of linear regression analysis to estimate the parameters of the I–V curve.","PeriodicalId":407958,"journal":{"name":"2016 Young Researchers in Vacuum Micro/Nano Electronics (VMNE-YR)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130819985","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}

In this paper the exact analytical solution to nonlinear problem of plane with elliptic inclusion is obtained. The constant nominal (Piola) stresses are given at infinity. Mechanical properties of plane and inclusion are modeling by harmonic semi-linear material. The stresses and displacements are expressed through two analytic functions of a complex variable, which are defined from nonlinear boundary conditions. Acceptance of a hypothesis, that nominal stress tensor is constant inside inclusion, has allowed to reduce a difficult problem of interface of two elastic bodies to the solution of two more simple problems for a plane with an elliptic hole. Validity of this hypothesis is proved to that obtained solution precisely satisfies to all equations and boundary conditions of a problem. The nominal hoop stresses were calculated on an interface of plane and inclusion for different material parameters.","PeriodicalId":407958,"journal":{"name":"2016 Young Researchers in Vacuum Micro/Nano Electronics (VMNE-YR)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124385100","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}
