Boundary Integral Formulations for Transient Linear Thermoelasticity with Combined-Type Boundary Conditions

نویسندگان

چکیده

We study boundary integral formulations for an interior/exterior initial value problem arising from the thermo-elasto-dynamic equations in a homogeneous and isotropic domain. The time dependence is handled, based on Lubich's approach, through passage to Laplace focus cases where one of unknown fields satisfies Dirichlet condition, while other subject conditions Neumann type. In domain, combined simple- double-layer potential operators are introduced proven be coercive. Based domain estimates, it possible prove existence uniqueness solutions This analysis complements previous results that may serve as mathematical foundation discretization schemes use element method convolution quadrature.

Higher order multi-point fractional boundary value problems with integral boundary conditions

In this paper, we concerned with positive solutions for higher order m-point nonlinear fractional boundary value problems with integral boundary conditions. We establish the criteria for the existence of at least one, two and three positive solutions for higher order m-point nonlinear fractional boundary value problems with integral boundary conditions by using a result from the theory of fixed...

About One Sweep Algorithm for Solving Linear-Quadratic Optimization Problem with Unseparated Two-Point Boundary Conditions

In the paper a linear-quadratic optimization problem (LCTOR) with unseparated two-point boundary conditions is considered. To solve this problem is proposed a new sweep algorithm which increases doubles the dimension of the original system. In contrast to the well-known methods, here it refuses to solve linear matrix and nonlinear Riccati equations, since the solution of such multi-point optimi...

Impedance boundary conditions for general transient hemodynamics.

We discuss the implementation and calibration of a new generalized structured tree boundary condition for hemodynamics. The main idea is to approximate the impedance corresponding to the vessels downstream from a specific outlet. Unlike previous impedance conditions, the one considered here is applicable to general transient flows as opposed to periodic ones only. The physiological character of...
