Application of methods of boundary and finite elements to analysis of tension concentration in two-dimensional and three-dimensional problems of elasticity theory

Methods of boundary and finite elements in mechanics of a deformed solid body are investigated in the paper aiming at the development of boundary element method (BEM) theory (the obtaining of the regularized integral relationships of a thermoelastic problem; the formula derivation of the half-analytical integration); the aglorithm elaboration of BEM and JEM synthesis; the program realization; the calculation of an ultracentrifuge rotor. As a result regularized integral relationships of a thermoelastic problem have been obtained. Formulae of the half-analytical integration have been derived. A modified algorithm of the BEM and FEM synthesis has been developed. The complex of applied programs has been realized. The calculation of an ultracentrifuge rotor has been held. The paper results have been introduced into operation in the design office (Moscow) for the execution of calculation investigations of ultracentrifuge rotorsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
