Over-deterministic method: The influence of rounding numbers on the accuracy of the values of Williams’ expansion terms [PDF]

open access: yesFracture and Structural Integrity, 2017
A study on the accuracy of the values of Williams’ expansion terms influenced by rounding numbers is presented. The results are presented taking into account a three-point bend single edge notched beam.

Propagation conditions of an eccentric crack in a semi-circular disk loaded in I+II mixed mode [PDF]

open access: yesMATEC Web of Conferences, 2020
Multi-parameter fracture mechanics concept is applied to investigate crack propagation conditions during a three-point bending (3PB) test performed on an asymmetrical semi-circular disk under I+II mixedmode loading.

Multi-parameter approximation of stress field in a cracked specimen using purpose-built Java applications [PDF]

open access: yesFracture and Structural Integrity, 2015
A quality of multi-parameter approximation of the stress and displacement fields around a crack tip in a non-brittle material test specimen is studied in the paper. The stress field approximation using Williams power series is intended to be utilized for

A Dual of the Compression-Expansion Fixed Point Theorems

open access: yesFixed Point Theory and Applications, 2007
This paper presents a dual of the fixed point theorems of compression and expansion of functional type as well as the original Leggett-Williams fixed point theorem. The multi-valued situation is also discussed.

One-man-band: Clough Williams-Ellis’ Architectural Ensemble at Portmeirion

open access: yesARENA Journal of Architectural Research, 2021
Portmeirion, a niche holiday resort in North Wales that was designed and built by Sir Clough Williams-Ellis from 1925 to 1976, is usually seen by architectural historians as an ‘idiosyncratic playground of little interest’.

An Isogeometric Over-Deterministic Method (IG-ODM) to Determine Elastic Stress Intensity Factor (SIF) and T-Stress

open access: yesMathematics, 2023
In order to examine the significance of Stress Intensity Factor and T-stress (K-T parameters) in modeling pressure-cracked structures, we propose a novel method known as the Isogeometric Over-Deterministic Method IG-ODM.

Multi-parameter fracture mechanics: crack path in a mixed-mode specimen

open access: yesFracture and Structural Integrity, 2019
A mixed-mode geometry has been chosen to investigate a crack propagation using the multi-parameter fracture mechanics concept. The so-called Williams series expansion is used for the crack-tip stress field approximation.

Right focal boundary value problems for difference equations [PDF]

open access: yesOpuscula Mathematica, 2010
An application is made of a new Avery et al. fixed point theorem of compression and expansion functional type in the spirit of the original fixed point work of Leggett and Williams, to obtain positive solutions of the second order right focal discrete ...
