Williams Expansion Terms and their Importance for Accurate Stress Field Description in Specimens with a Crack [PDF]
Transactions of the VŠB-Technical University of Ostrava, Mechanical Series, 2013 The paper deals with an analysis of the stress and displacement fields in various cracked specimens (loaded in mode I as well as in mode II). The main goal is to determine an accurate approximation of the near-crack-tip fields which can be subsequently

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

A Dual of the Compression-Expansion Fixed Point Theorems
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.
