Integro-differential equations with singular and hypersingular integrals

Proceedings of the National Academy of Sciences of Belarus. Physics and Mathematics Series, 2019
Quadrature linear integro-differential equations on a closed curve located in the complex plane are solved. The equations contain singular integrals which are understood in the sense of the main value and hypersingular integrals which are understood in the sense of the Hadamard finite part. The coefficients of the equations have a special structure.

The Singular Integral Equation Method in the Analysis of a Crack Perpendicular to the Interface: The Hypersingular Integral Equation Method and the Body Force Method

, 1989
In this paper, the plane problem of two bonded elastic half planes containing a crack perpendicular to and going through the interface is considered. The problem is formulated as a system of singular integral equations by using the stress field induced ...

Numerical Solutions of a Hypersingular Integral Equation with Application to Productivity Formulae of Horizontal Wells Producing At Constant Wellbore Pressure

, 2014
The performance of horizontal wells producing at constant wellbore pressure is a critical problem in petroleum engineering. But few articles on the well performance under constant wellbore pressure can be found in the literature due to the difficulty of ...

The boundary element method applied to static and dynamic crack problems using hypersingular boundary integral equations

, 1990
The need for hypersingular boundary integral equations in crack problems is motivated through acoustic and elastic wave scattering from a thin screen and crack. By integrating over a small (not necessarily symmetric) neighborhood about the singular point,
