WebJan 1, 2024 · The proposed method extends the recently developed delay-based max pressure (MP) algorithm by using the sum of cumulative delay experienced by all vehicles that joined a given link as the metric for weight calculation. Doing so ensures the movements with lower traffic loads have a higher chance of being served as their delay increases. WebA modiﬁed delay-and-sum algorithm is then proposed for detecting impact damage in composite plates with and without a stiffener which is shown to capture and localize damage with only four transducers. Keywords: damage detection, Lamb wave, structural health monitoring, composite stiffened panel, delay-and-sum algorithm
