摘要: The composite tidal turbine nozzle can be exposed to impact loads during maintenance or installation operations, which may result in invisible damage. Therefore, it is very important analyse the induced damage order conceive hybrid nozzles with better resistance low-velocity behaviour (LVI) of a carbon/glass has been investigated based on this motivation. configurations stacking sequences were constituted glass and carbon fibers. results acquired compared between five various laminated. Indeed, was studied leading edge region nozzle. damaged laminates inspected by finite element method (FEM) Hashin failure criterion using ABAQUS software. energy conservation verified validate numerical model. Futhermore, effect accidental dynamic response have investigated. According results, formation like matrix cracking external/internal surfaces radial occur. In addition, CCC (carbon/carbon/carbon), CGG (carbon/glass/glass) greater other configurations.
