Abstract
A discussion of the author’s advanced viewpoint on the underlying principles for construction of Godunov’s scheme is presented. The application of these principles in problems of elastic and elastoplastic deformations is outlined. The presentation is based on extensive numerical simulations performed for both an analysis of the solution convergence details with decreasing mesh step size (for equations of Fluid Dynamics) and the motivation of modeling an elastoplastic media by an “effective elastic deformation” and the employment of Maxwell’s viscosities.
