Two-dimensional problems of deformed rigid body mechanics

A deformed rigid body with elastic, viscoelastic or viscoplastic properties is considered in the paper aiming at the effective mathematical body creation of the boundary-value problem formalization for two-dimensional singly connected objects. The solution of the complex of arising mathematical problems is also the aim of the paper. As a result the convenient and effective method of boundary representations for the description and processing of the mechanics boundary-value problem solution has been developed. Mathematical methods of the boundary-value problem solution for homogeneous and heterogeneous biharmonic equations have been created. A model of a viscoplastic medium has been described in "complex variables". New applied problems of the deformed rigid body mechanics have been solved. The methods developed may be introduced into the practice of strength analysis and technological regime design of the metal processing by pressure, they may be the standard for estimation of engineering methodsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
