The objective of the research is development of methods and approaches for the mathematical modeling of inhomogeneous structures and nonlinear materials and development of software for numerical simulation of three-dimensional problems of structural mechanics of inhomogeneous and nonlinear materials under static and dynamic deformation. The approach is based on the methods of perturbation and phase integrals. Using these methods, we solve nonlinear singular differential equations with variable coefficients with a high degree of non-linearity. Using the moment scheme for the finite element method, we investigate the stress-strain state of the rubber isolator and the string-ribbon. In addition, in we investigate influence of cracks on the state of these objects.
