A computational iterative design method for bend-twist deformation in composite ship propeller blades for thrusters
Rokvam, Sondre Østli; Vedvik, Nils-Petter; Mark, Lukas; Rømcke, Eivind; Ølnes, Jon; Savio, Luca; Echtermeyer, Andreas Thorsten (Peer reviewed; Journal article, 2023)This study investigates the feasibility of utilising common composite material layup techniques in ship propeller blade design to achieve an automatic pitch adjustment through bending-induced twist deformation. A comprehensive ... -
Designing Composite Adaptive Propeller Blades with Passive Bend–Twist Deformation for Periodic-Load Variations Using Multiple Design Concepts
Rokvam, Sondre Østli; Vedvik, Nils-Petter; Savio, Luca; Echtermeyer, Andreas Thorsten (Peer reviewed; Journal article, 2023)Four plausible design concepts are applied together to investigate composite bend–twist propeller-blade designs that show high twisting per bending deflection. The design concepts are first explained on a simplified blade ... -
Nondestructive Inspection of Thick Multi-Layered Thermoplastic Composite Pipes
Bin Mohd Tahir, Mohd Fadzil; Pors, Guillaume; Echtermeyer, Andreas Thorsten (Chapter, 2024)A collaborative effort is underway to establish standardized methods for ensuring the structural integrity of composite pipes, focusing on thick fiber-reinforced composite pipes like thermoplastic composite pipe (TCP) and ... -
Phased Array Ultrasonic Testing on Thick Glass Fiber Reinforced Thermoplastic Composite Pipe Implementing the Classical Time-Corrected Gain Method
Mohd Tahir, Mohd Fadzil; Echtermeyer, Andreas Thorsten (Peer reviewed; Journal article, 2024)Thermoplastic composite pipe is gaining popularity in the oil and gas and renewable energy industries as an alternative to traditional metal pipe mainly due to its capability of being spooled onto a reel and exceptional ... -
Progressive Fatigue Modelling of Open-Hole Glass-Fibre Epoxy Laminates
Maneval, Victor; Vedvik, Nils-Petter; Echtermeyer, Andreas Thorsten (Peer reviewed; Journal article, 2023)The failure of composite laminates under cyclic fatigue loads is complex, as multiple failure mechanisms are in play at different scales and interact with each other. Predicting the remaining fatigue life as well as the ... -
Thermomechanical properties of zirconium tungstate/hydrogenated nitrile butadiene rubber (HNBR) composites for low-temperature applications
Akulichev, Anton; Alcock, Benjamin; Tiwari, Avinash; Echtermeyer, Andreas Thorsten (Journal article; Peer reviewed, 2016)Rubber compounds for pressure sealing application typically have inferior dimensional stability with temperature fluctuations compared with their steel counterparts. This effect may result in seal leakage failures when ...
