Многоточечные приближения высших порядков в краевой задаче упругости полидисперсных композитов со случайной структурой

The problem of calculation of stress and strain fields in 3D matrix composites is considered. Random structure of composites is described with set of multipoint moment functions. Boundary-value problem is reduced to integral-differential equation, which is solved in the second approximation. The method of obtaining of analytical expressions for stress and strain fields statistical characteristics is presented.
