Abstract: Abstract A combined experimental-numerical method is proposed to predict the mechanical behavior of composite overwrapped pressure vessels under impact conditions. Material characterization tests are conducted on filament-wound samples to determine the key material parameters, whilst…

Abstract: The equivalence of quasi-static indentation and low-velocity impact loading regimes has been assessed for composite overwrapped pressure vessels. Test specimens were assessed in detail in terms of the force–displacement response, and micro-focus computed tomography was…

Abstract: In order to verify the delamination damage occurring in thick-walled composite-overwrapped pressure vessels, firstly, for composite delamination damage, a composite laminate model was established. Model I and model II delamination failure processes of composite structures…

Abstract: This paper characterizes laser-generated guided waves in a metal-lined composite-overwrapped pressure vessel (COPV) to assess typical damage, including interfacial debonding and low-velocity impact damage. First, an eigenfrequency approach that avoids additional coding is utilized to…
