Simultaneous pairs of dual integral equations [PDF]

open access: yes, 1965
A fruitful method of attack in the solution of mixed boundary value problems is the utilization of integral transform techniques. Satisfaction of the mixed boundary conditions then leads to consideration of one or more pairs of dual integral equations ...

Visualizing the crack driving force through fluid analogy

open access: yesJournal of the Mechanical Behavior of Materials, 2019
It is shown that the crack driving force for a fundamental antiplane crack problem is analogous to the limiting case of the force acting on an ideal fluid on free streamlines that form at the ends of flow around two parallel plates.

Effect of hold time on creep-fatigue crack propagation in lead-free solder

open access: yesNihon Kikai Gakkai ronbunshu, 2015
Crack propagation tests of lead-free solder were conducted using center-notched plates under load- and displacement-controlled conditions of cyclic tension-compression. Four waveforms were adopted for tests: pp waveform having fast loading and unloading,

Crack Driving Force Calculation for a Railway Wheel Considering Thermoplastic Properties of the Wheel Material [PDF]

open access: yesInternational Journal of Railway Research, 2020
In this paper, the driving force calculation of a cracked railway wheel is studied, and the effects of thermal loads due to braking, train speed, and elastic-plastic material model are considered.

An extended J-integral for evaluating fluid-driven cracks in hydraulic fracturing

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2018
J-integral has served as a powerful tool in characterizing crack tip status. The main feature, i.e. path-independence, makes it one of the foremost fracture parameters.

An IGA based domain integral method for the evaluation of the J-integral using the singular patch method

open access: yesMechanical Engineering Journal, 2022
In this paper, a domain integral method to evaluate the J-integral along with a singular patch method for three-dimensional linear elastic fracture mechanics analyses using Isogeometric analysis (IGA) are presented.

Some results on top local cohomology modules with respect to a pair of ideals [PDF]

open access: yesMathematica Bohemica, 2020
Let $I$ and $J$ be ideals of a Noetherian local ring $(R,\mathfrak m)$ and let $M$ be a nonzero finitely generated $R$-module. We study the relation between the vanishing of $H_{I,J}^{\dim M}(M)$ and the comparison of certain ideal topologies.

Periodicity of non-central integral arrangements modulo positive integers [PDF]

open access: yes, 2008
An integral coefficient matrix determines an integral arrangement of hyperplanes in R^m. After modulo q reduction, the same matrix determines an arrangement A_q of "hyperplanes" in Z^m.

Vinogradov systems with a slice off [PDF]

open access: yes, 2017
Let $I_{s,k,r}(X)$ denote the number of integral solutions of the modified Vinogradov system of equations $$x_1^j+\ldots +x_s^j=y_1^j+\ldots +y_s^j\quad (\text{$1\le j\le k$, $j\ne r$}),$$ with $1\le x_i,y_i\le X$ $(1\le i\le s)$.
