What is architectural glass delamination?

Answer from top 1 papers

Architectural glass delamination refers to the separation of layers in laminated glass, a material commonly used in modern architecture. Delamination can compromise the structural integrity and aesthetic qualities of glass installations in buildings ( and ).
Interestingly, while delamination is a known issue in the use of laminated glass, advancements in the understanding of glass properties, lamination techniques, and finite element modeling have allowed for its broader architectural application, including large-scale structures and facades (). Delamination can be influenced by factors such as the boundary conditions of the glass installation, the properties of the interlayer material, and the manufacturing process ( and ). Additionally, the compatibility of glass with other materials is crucial, as incompatibility can lead to degradation and delamination, posing risks to structural performance and health ().
In conclusion, while delamination presents challenges to the use of laminated glass in architecture, ongoing research and technological developments are addressing these issues to ensure the safe and effective use of glass as a structural material. The findings from studies on delamination can inform design and manufacturing processes to mitigate risks and enhance the durability of glass installations ( and ).

Delamination of coatings and thin films from substrates generates a fascinating variety of patterns, from circular blisters to wrinkles and labyrinth domains, in a way that is not completely understood. We report on large-scale numerical simulations of the universal problem of avoidance and coalescence of delamination wrinkles, focusing on a case study of graphene sheets on patterned substrates. By nucleating and growing wrinkles in a controlled way, we are able to characterize how their interactions, mediated by long-range stress fields, determine their formation and morphology. We also study how the interplay between geometry and stresses drives a universal transition from conformation to delamination when sheets are deposited on particle-decorated substrates. Our results are directly applicable to strain engineering of graphene and also uncover universal phenomena observed at all scales, as for example in geomembrane deposition.
