Fatigue Life Estimation of Bridges with Smart Mobile Sensing

Bridges undergo significant vibrations and repeated stress variations during their operational life. Fatigue cracking and eventual fatigue failure of bridges are possible outcomes, highlighting the need for scalable life cycle analysis to estimate the remaining useful life of a structure accurately. Fatigue life is typically estimated by the number of stress cycles a structure can withstand before failure. Engineers traditionally use strain gauges—sensors that measure changes in force or stress applied to an object—to collect...
