The satellite's librational motion near gravitationally stable equilibrium position is investigated. With taking into account the non-linear terms up to the third order of smallness the spectral structure of the Lorentz torque is analyzed. Possible resonant combinations due to the disturbing torque in the attitude motion of gravity oriented satellite are revealed. Relevant curves are plotted on the plane of the dimensionless inertial parameters of the satellite.","PeriodicalId":194578,"journal":{"name":"2015 International Conference on Mechanics - Seventh Polyakhov's Reading","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128061562","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 plane problem (plane strain or plane stress) for bi-material plate with elliptic hole is considered. On the boundary of the hole an external load is applied. At infinity constant stresses are given. The proximity of the hole to interface renders essential influence on the magnitude of stresses near the hole and on the interface. For engineering applications it is important to know fields of stresses and displacements. The method of Kolosov-Muskhelishvili complex potentials and the method of superposition are used for the solution of the problem.

Formulae governing the motion of particles in the main stream are found in the form of third-order polynomials. In the presence of a screening layer near the surface, the capture of particles can occur. In such a case, the particle drift along the emitting surface can also occur due to a small horizontal component of the force field.
