Abstract
The purpose of this scientific-essay is constructionation numerical dynamical task solving algorithm of multilayered discretely substantiated shells, that based on using Richardson finite-difference approximations types. Multilayered discretely substantiated shells refer to complex nonuniformity by thickness elasticity-structures. In one reason, nonuniformity existed because of shell-flakiness structure, in other case – because of existing discretely substantiated edges. Including the discretely count of substantiated elements brings to exist new bursting coefficients on spatial coordinates in output equations. Numerical method usage (finite-dіfference method, finite-elements method etc.) for solving dynamic-progressions tasks in listed structures observing convergence of the worsening numerical results. For the constructing more effective numerical algorithms used the method, which based on finding approximation solutions by Richardson.
