Resumo(s): | A numerical methodology was implemented to support the development of adhesive spreading patterns for the Optical Bonding (OB) material on display bonding process, in order to reduce the experimental trial and error effort, being this iterative process done mainly through numerical simulations. These simulations were performed using the commercial software Abaqus, more specifically the Abaqus/Explicit module, which includes the Coupled Eulerian-Lagrangian method (CEL), used in cases where extreme deformations of the material are observed. This way, it was possible to obtain a methodology capable of predicting the spreading behaviour of a predefined OB material pattern. These results were initially compared to experimental results for a simple validation case and later for two more complex real cases. The numerical approach developed provided results very close to what was observed in experimental tests. This methodology can be a useful tool to optimize OB material patterns for display bonding process, but the simulation time needed is still a concern to have in mind. |
