Краткое описание

A method for solving plane nonstationary problems on the effect of surface loads on a half-space filled with a nanosized micropolar material structure, whose model is the Cosserat continuum, is developed. The approach suggested is based on the principle of superposition in combination with the small parameter method, with the small parameter being represented by one of the micropolar material constants. A boundary resolving integral representation, whose nucleus is the surface function of the effect of the half-space filled with a micropolar medium, is built. A numerical algorithm for computation of normal displacements of the half-space surface, which is based on the method of weight coefficients, has been developed and implemented. Examples of computations are given.
