Journal ArticleDOI
Hypersingular integrals: how smooth must the density be?
Paul A. Martin,Frank J. Rizzo +1 more
TL;DR: In this paper, it is shown that for one-dimensional Hadamard finite-part integrals, the even part of the integrand has a Holder-continuous first derivative, while the odd part is discontinuous.
Journal ArticleDOI
A Method for Stress Determination in Plane Anisotropic Elastic Bodies
Frank J. Rizzo,D. J. Shippy +1 more
TL;DR: In this article, a real variable integral formula of the Somigliana type is derived for linear anisotropic elasticity, which relates an elastic displace field to boundary traction and displacement vectors; all refer to an arbitrary equilibrated stress state present in an orthotropic body of arbitrary shape and connectivity.
Journal ArticleDOI
Boundary integral equations for thin bodies
TL;DR: In this paper, a mixed formulation for a thin rigid scatterer which combines CBIE and HBIE is motivated by examining the discretized form of the integral equations, and this formulation is shown to be nondegenerate for thin non-rigid inclusion problems.
Journal ArticleDOI
On the numerical solution of two-dimensional potential problems by an improved boundary integral equation method☆
TL;DR: The use of piecewise quadratic polynomial approximations in the boundary integral equation method for the solution of boundary value problems involving Laplace's equation and certain Poisson equations is described in this paper.
Journal ArticleDOI
On time-harmonic elastic-wave analysis by the boundary element method for moderate to high frequencies
TL;DR: In this paper, some procedures for obtaining accurate boundary element solutions to problems of elastodynamics at moderate to high frequencies are described. And the use of these procedures in solving transient problems via Fourier transform inversion is illustrated.
