1. Application of Differential Geometry to Elasticity and Corresponding Discrete Models
Abstract : The amazing development in technology and industry during the last half of the twentieth century has opened totally new research fields. One of them is computational mechanics. Suddenly very complex, three-dimensional nonlinear engineering problems could be solved as a consequence of explosive advances in computers and numerical schemes. READ MORE

2. Analytic Element Models for Groundwater Flow and Linear Elasticity in Fractured Rocks
Abstract : There is an increasing demand for using deep underground space at various scales, such as small-scale geothermal wells and large-scale projects like tunnels or nuclear waste disposal. The deep underground space in fractured rock is a heterogeneous and challenging medium. READ MORE

3. A generalized finite element method for linear thermoelasticity
Abstract : In this thesis we develop a generalized finite element method for linear thermoelasticity problems, modeling displacement and temperature in an elastic body. We focus on strongly heterogeneous materials, like composites. READ MORE

4. Model Adaptivity in Elasticity
Abstract : We consider model adaptivity in elasticity for dimensionally reduced forms, and shall treat different conceptual approaches. The basic idea, however, is to adaptively refine, not only the computational mesh, but also the underlying mathematical formulation. READ MORE

5. Solution to boundary-contact problems of elasticity in mathematical models of the printing-plate contact system for flexographic printing
Abstract : Boundary-contact problems (BCPs) are studied within the frames ofclassical mathematical theory of elasticity and plasticityelaborated by Landau, Kupradze, Timoshenko, Goodier, Fichera andmany others on the basis of analysis of two- and three-dimensionalboundary value problems for linear partial differential equations.A great attention is traditionally paid both to theoreticalinvestigations using variational methods and boundary singularintegral equations (Muskhelishvili) and construction of solutionsin the form that admit efficient numerical evaluation (Kupradze).
