LAMINATED GLASS STRUCTURES IN BENDING: TIME/TEMPERATURE-DEPENDENT FINITE ELEMENT MODELS
Original language description
The lamination of glass sheets with ductile interlayers significantly changes the post-fracture response of glass structures and increases their safety. The aspects important for the modeling of laminated glass structures are: (i) heterogeneity in material parameters of glass and polymer foil (the ratio of shear moduli exceeds 1,000), (ii) time/temperature-dependent behavior of polymer foil, and (iii) effects of geometric non-linearity as a result of slenderness of laminated glass. One of the modeling approaches is finite element formulation based on refined theories. In the proposed model, kinematics relations are formulated for each layer individually and the compatibility on the interfaces of layers is ensured via Lagrange multipliers with the meaning of forces holding the neighboring layers perfectly bonded. The comparison of models with different assumptions is performed in this contribution: formulation based on large deflection or finite strains theories for kinematics, and constitutive assumption of constant bulk modulus or constant Poisson's ratio in relations for time/temperature-dependent behavior of polymeric interlayer. The developed models were verified against the detailed finite element model in ADINA and compared with a simplified model assuming elastic behavior of polymer foil with the secant shear modulus set according given temperature and loading time.
