Linear dynamic properties in curved laminated glasses

The study presents the results of linear dynamics laminated glass panels with different curvatures. This is an actual task in field mechanical engineering, aviation, shipbuilding, energy, architecture, etc. Such composites are durable, easy to care for and have a wide range design options. aim work influence curvature parameter on frequencies modes composites. paper considers characteristics polyvinyl butyral interlayer. article behavior triplex propagation elastic waves state. performs calculations using finite element method framework modal analysis three-dimensional formulation physical linear-elastic formulation. uses hexagonal 8 nodes 3 degrees freedom each. model ranging from 0 mm 250 mm. composite consisted three layers: two layers thickness each was mm, interlayer 0.38 thickness. size plates 500×500 As boundary condition, laminate fixed opposite sides. mesh convergence analysis. natural accordance derived. graphs vibration also shown, that give clear view about state
