Significance of Higher-order Terms of the Williams Expansion for Plastic Zone Extent Estimation Demonstrated on a Mixed-mode Geometry [PDF]
, 2014 In this work, the multi-parameter description of the crack-tip fields is employed. The Williams expansion is introduced for approximation of the stress/displacement distribution.

Vestnik of Samara University. Natural Science Series, 2022 In the present study the asymptotic analysis of the multi-parameter Williams series expansion of the stress-strain state in the vicinity of seven different configurations is performed. The aim of the asymptotic analysis is to educate the sensitivity of different cracked and notched configurations to the number of kept terms in Williams series expansion.

A Dual of the Compression-Expansion Fixed Point Theorems [PDF]
Fixed 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.

From Muskhelishvili Potentials to Williams Expansion of Crack-Tip Stress Fields
The Williams expansion provides a fundamental asymptotic description of crack-tip stress fields in linear elastic fracture mechanics, where the leading singular term governs K-dominance and the non-singular and higher-order terms control crack-tip constraint and deviations from near-tip asymptotics.

Late phonological development in Williams syndrome [PDF]
Frontiers in Psychology, 2022 Williams syndrome is a neurodevelopmental genetic disorder characterized by a unique phenotype, including mild to moderate intellectual disability and an uneven neuropsychological profile of relative strengths and weaknesses.

Key Engineering Materials, 2013 The domain of the generalized stress intensity factors dominance ahead of the notch tip can be rather small with respect to the length of the perturbing cracks initiated from the tip of the notch. Thus the non-singular terms of the stress asymptotic expansion at the notch tip would play an important role in the notch tip stability.
