Structural Health Diagnosis and Prognostics Using Fatique and Crack Growth Monitoring

摘要: Abstract : Fatigue damage sensing and crack propagation monitoring of any structure is a prerequisite for reliable effective structural health monitoring. This paper, discusses the role two different sensors, i.e., (CP) fatigue (FD) sensors in The CP sensor capable detecting initiation subsequent within component that essentially constitutes diagnostics approach. FD monitors actual can be used both diagnosis prognosis remaining useful life. bonded to at critical location progression surface breaking through successive strands, resulting an increase total resistance having alternate slots strips with strain magnification factor respect nominal its location. designed such experience strains which closely resemble distribution area component. One major advantages this it placed convenient location, still experiencing same as An interesting aspect these they are easily integrated wireless networking, facilitating ease use real time data acquisition. Both could applied various structures from ground civilian military vehicles steel bridges. predict life or number miles (for automobile) left before needed replacement.
