System research and information technologies| Zusammenfassung: | On the basis of mathematical modeling, the stress state of an orthotropic electro-elastic space with a spheroidal cavity under internal pressure is investigated. The solution of the problem is obtained by using the Eshelby equivalent method, generalized to the case of an orthotropic piezoelectric material, and the integral representation of the Green’s function for an orthotropic electroelastic space. Testing of the algorithm for solving the problem for a special case (for a transversely isotropic electrical-elastic material with a spheroidal cavity) confirms its effectiveness. The numerical studies of the stress state in an orthotropic electroelastic material with a cavity under internal pressure were carried out, characteristic patterns of the stress distribution were found. |
