Outline of Final Research Achievements |
Thermo-elastic system describes a relation between elastic deformation and distribution of temperature. It is represented by the system of nonlinear partial differential equations for displacement vector and temperature. We studied equations related to the system. Our results for this research subject are as follows: (1) higher order asymptotic expansion of solution for the weakly damped isothermal Falk-Konopka model of three-dimensional shape memory alloys, (2) construction of two kinds of invariant measure for the isothermal Falk model, (3) singular limit problem for the Woinowsky-Krieger equation of extensible beam equation, (4) energy methods for the structure-preserving finite difference schemes of the Falk model and other equations.
