A Simple Transformation for Near-Singular Integrals on Curvilinear Elements

IEEE Transactions on Antennas and Propagation, 2015
It is difficult to evaluate the near-singular four-dimensional integrals in the Galerkin magnetic-field integral equations (MFIE), especially for the curvilinear elements. This communication presents a hyperbolic transformation to cancel the near singularities in the ${\bf 1}/{{\bm {R}}^{\bf 2}}$ kernel on curved quadrilateral elements, which is ...

Quadrature formulae for the Hadamard integral over a curvilinear surface

Russian Journal of Numerical Analysis and Mathematical Modelling, 1998
The authors construct a quadrature formula for integrals of the type \[ \frac{1}{4\pi} \int_\sigma \frac{\nu(M_0) d\sigma_{M_0}}{| M_0M| ^3} , \] where \(\sigma\) is a differentiable manifold with boundary, \(M_0\), \(M \in \sigma\), \(\nu(M_0)\) is a sufficiently smooth function, and \(| M_0 M| \) is the distance between \(M\) and \(M_0\).

The curvilinear integral method: a question to the critical plane concept

International Journal of Fatigue, 1997
Abstract There are many supporters of the critical plane concept who try to formulate the most adequate critical plane measure, reduce multiaxial loading components to critical plane stressing and predict fatigue life irrespective of how stressed the rest of the planes are. A simple question then occurs: would the life be the same if, in a ‘maximized’

Robust variational inequalities governed by curvilinear integral functionals

Journal of Nonlinear and Variational Analysis
Summary: In this paper, we state that generalized convexity, invex sets, and the Fréchet differentiability assumption associated with curvilinear integral type functionals represent some necessary and sufficient mathematical tools for establishing various connections between the solutions of some robust (weak) vector commanded variational inequalities ...
