An approach to the test design for smart composite vessels enabling remaining useful life estimation

This paper proposes a methodological approach for designing smart composite hydrogen tanks using strain gauges and finite element analysis for continuous structural health monitoring. Simulation identifies critical stress points to optimize sensor placement. Laboratory burst and cyclic tests provide a baseline and proof of concept for a remaining useful life analysis, improving safety and resource efficiency in hydrogen storage. Results demonstrate that strain data reflect stress patterns and material responses, supporting effective monitoring of tank condition during pressurization cycles.
