Determination of the intensity of singularity at the vertex of interface in three-dimensional joints using a conservative integral (Effect of radius of integral domain and size of element)

open access: yesNihon Kikai Gakkai ronbunshu, 2015
Singular stress occurs at the vertex of interface in three-dimensional joint structures under an external force and a temperature variation. It is very important to estimate the intensity of singularity for evaluating the strength of joints.

Explicit Solution of the Time Domain Volume Integral Equation Using a Stable Predictor-Corrector Scheme [PDF]

open access: yes, 2012
An explicit marching-on-in-time (MOT) scheme for solving the time domain volume integral equation is presented. The proposed method achieves its stability by employing, at each time step, a corrector scheme, which updates/corrects fields computed by the ...

Localized boundary-domain integral formulations for problems with variable coefficients [PDF]

open access: yes, 2002
Specially constructed localized parametrixes are used in this paper instead of a fundamental solution to reduce a boundary value problem with variable coefficients to a localized boundary-domain integral or integro-differential equation (LBDIE or LBDIDE).
