Fatigue Behavior of High‐Performance Concrete

Journal of Materials in Civil Engineering, 1993
A fatigue study was performed two commercial high-strength concretes of 70 MPa and 95 MPa with water/cementitious material ratios of 0.28 and 0.23, respectively. Specimens were cast at the construction site and cured in the laboratory. Tests were performed under constant amplitude, and strains were measured continuously using strain gauges.

Crew Fatigue Safety Performance Indicators for Fatigue Risk Management Systems

Aviation, Space, and Environmental Medicine, 2014
Implementation of Fatigue Risk Management Systems (FRMS) is gaining momentum; however, agreed safety performance indicators (SPIs) are lacking. This paper proposes an initial set of SPIs based on measures of crewmember sleep, performance, and subjective fatigue and sleepiness, together with methods for interpreting them.Data were included from 133 ...

Fatigue performance of repaired aluminium panels

International Journal of Fatigue, 1993
Fatigue lives of some pre-cracked 7075-T6 aluminum panels that had been repaired using four different repair techniques have been investigated. The panels were repaired by patching over the cracks either with aluminum plates using rivets or with car bon/epoxy composite patches using adhesive.
