Design considerations in composite flexible hinges with circular and aerofoil cross-sections

open access: yes, 2022
Cylindrical shells behave nonlinearly under bending. This geometrical non-linearity, known as the Brazier effect, is accompanied by instability which can be exploited for the hinge-less folding of cylindrical shells; i.e. it enables flexible hinges to be

Pre-test Cortisol Levels in Predicting Short Synacthen Test Outcome: A Retrospective Analysis

open access: yesClinical Medicine Insights: Endocrinology and Diabetes, 2022
Objective: Short Synacthen tests (SSTs) are expensive, dependent on Synacthen availability, and need supervision. To reduce SST testing, we examined the utility of pre-test cortisol (Cort0) and related parameters in predicting outcome.

Shape optimisation of cold roll formed sections considering effects of cold working

open access: yes, 2021
The design development of new cold roll formed sections can lead to a significant reduction in material costs if the sections are optimised for strength performance considering the effect of shapes and change of material properties by cold working during
