ABSTRACT
Composite overlay patches are bonded to damaged or undamaged marine structure as a means to improve or restore damage tolerance and load-carrying capacity. While this repair and reinforcement method is currently demonstrated on marine structures around the globe, design and analysis methodologies that account for the high variability in design parameters, material properties, and loading conditions are lagging behind its implementation. In order to optimize patch design and to ensure safe performance during the lifecycle of the patch, a comprehensive understanding of the effects of uncertainty on patch performance is essential. This work demonstrates an approach based on sensitivity analysis to quantify the influence of composite overlay design parameters on structural performance.
