Effect of Microstructure on Mechanical Properties of High Strength Steel Weld Metals [PDF]

open access: yes, 2004
The effects of variations in alloying content on the microstructure and mechanical properties of high strength steel weld metals have been studied. Based on neural network modelling, weld metals were produced using shielded metal arc welding with nickel ...

Mechanical strength of tooth fragment reattachment

open access: yesJournal of Biomedical Materials Research, 2001
The aim of this study was static and fatigue test investigation of the strength of a tooth fragment reattached with adhesives to the tooth body. Central bovine incisor teeth were used, and standardized fragments were obtained by cutting the incisal edge of the selected teeth.

Systematic numerical investigation of the role of hierarchy in heterogeneous bio-inspired materials [PDF]

open access: yes, 2012
It is well known that hierarchical structure is an important feature in biological materials to optimise various properties, including mechanical ones. It is however still unclear how these hierarchical architectures can improve material characteristics,

Investigation of strength recovery of recycled heat treated glass fibres through chemical treatments [PDF]

open access: yes, 2013
The strength loss of thermally treated glass fibre (GF) at elevated temperature is well reported in literature. This phenomenon even occurs at short period of time such as 25 minutes.

Experimental Research on Wind-Induced Flag-Swing Piezoelectric Energy Harvesters

open access: yesShock and Vibration, 2021
Piezoelectric cantilever beams, which have simple structures and excellent mechanical/electrical coupling characteristics, are widely applied in energy harvesting. When the piezoelectric cantilever beam is in a wind field, we should consider not only the
