摘要:Abstract(#br)In this paper, we consider the initial-boundary value problem for a nonlinear Kirchhoff type equation with the damping term and spring boundary conditions. We establish the global existence and uniqueness of solutions to this problem in time, and give an example an...

摘要:... Various ways of substituting such layers by some effective boundary conditions have been proposed, and these are briefly reviewed. A rational way of obtaining boundary conditions that are exact to first order in the layer thickness is then described. For a thin spherical l...

摘要:... The presented approach is an extension of the boundary integral equation method (BIEM) based on the boundary integral approach. Periodically situated delaminations are simulated via spring boundary conditions (SBCs), which allows considering bridged cracks. A boundary integra...

摘要:Abstract(#br)In the present study frequency dependent effective spring boundary conditions are formulated to simulate wave propagation through an interface with distributions of micro-cracks of various sizes. The frequency dependent formulae for spring stiffnesses are obtained...

摘要:Abstract(#br)The possibility is studied of applying spring boundary conditions to describe propagation of elastic waves in layered composites with nonperfect contact of components or in the presence of groups of microdefects at the interface. Stiffnesses in spring boundary conditions...

摘要:The elastic spring boundary conditions play an important role in dynamical analysis of functionally graded (FG) nanorods. However, these special issues have not been properly paid attention to in the previously developed non-local models. In this work, longitudinal vibration anal...

摘要:... The damaged is modeled as a stochastic distribution of equally sized circular cracks which is transformed into a spring boundary condition. First the scattering by a single circular interface crack between two dissimilar half-spaces is investigated and solved explicitly for n...
