Creep Deformations of Curvilinear Anisotropic Media: Finite Element Modeling

Abstract

Abstract This paper proposes a method for preliminary analysis of layer daynamics, it composition and assessment of deep-seated rock. Since physical knowledge is insufficient or the cannot be experimentally obtained, the phase of development and industrial launch of wells, mines, and open pits is nesessary. The method based on modeling the stress-strain state of rocks includes block-curvilinear anisotropy and creep. We develop methods that qualitatively describe the non-standard geometric shapes of deep rock layers. A block-curvilinear description of the rock model is given. We also offer the method for the effective numerical solution to the stress-strain state considering block-curvilinear anisotropy and creep. The software application is designed in the Scientific and Educational Center Supercomputer Engineering Modeling and Development of Software Systems at Bauman Moscow State Technical University (BMSTU). This software application helps to create, describe, solve and analyze both rocks and other mathematical models, as well as creep equation.
