“…The intermediate film acts as an elastic layer to dissipate some of the energy when the glass is impacted. 4 The bonding strength and mechanical properties of the intermediate film are required on account of application direction of laminated glass. 5 The common intermediate materials include ethylene vinyl acetate (EVA), polyvinyl butyral (PVB), thermoplastic polyurethane (TPU), etc.…”

Compared with the traditional polyvinyl butyral (PVB) laminated glass, the polyurethane (PU) based laminated glass has the advantages of higher impact strength and longer service life. Thus, aromatic polyurethane films have attracted more attentions in recent years due to their high light transmittance, adhesion and functionality. In this paper, the tensile strength of polyurethane films based on bis(4‐isocyanatocyclohexyl)‐methane (HMDI) have been increased from 27 to 51 MPa and their elongation at break have been increased from 330% to 525% after solvent annealing in toluene. It is attributed to molecular segments with high crystallization and hydrogen bond formation of PU, which are confirmed by FT‐IR and XRD characterization. Based on this, laminated glasses with higher impact strength based on the thermoplastic polyurethane films are constructed successfully.

“…The details about the FDEM can be found in the literatures [25][26][27]. Recently, the FDEM has been used to simulate the failure of brittle/quasi-brittle solids under static/quasi-static and dynamic loads [28][29][30][31][32][33]. Regarding the failure of masonry structures, Chen et al [34] employed the FDEM to investigate the collapse of dry-jointed masonry arches subjected to support movement, and investigated the effects of geometry and friction coefficient.…”

Historic masonry heritages, such as cathedrals, colonnades, and arch bridges, were constructed with individual components (e.g., stones, bricks, other materials) bound together with, e.g., mortar, and they are very vulnerable to foundation settlement, especially differential settlement which occurs frequently in engineering practice. These masonry structures are discontinuous, and therefore, their behavior under differential settlement is highly nonlinear and complex. In this study, the combined finite-discrete element method (FDEM) is employed to simulate the failure behavior of historic masonry heritages subjected to support differential settlement. In the FDEM models, structures are discretized into elements where FE formulation is incorporated, resulting in an accurate estimate of structural deformation and interaction forces. In addition, a fracture model is employed for masonry blocks. Numerical examples are given and compared with results from the literature, showing that the FDEM is applicable and reliable in simulating the failure behavior of historic masonry heritages. Further analyses including block fracture reveal that fracturing can decrease the capacity against settlement significantly.

“…Many models have been proposed concerning the indentation of laminated glass windscreens. Dierent approaches are reviewed and the results regarding the crack evolution and the brittle material response are compared [11]: nite element modeling (FEM) [5,12,13,14] using cohesive zone models [15,16,17], extended nite element modeling (XFEM) [18], the mixed nite-discrete elements [19,20], and peridynamics [21,22]. However, most of these studies focus on the head-form or hard-body blunt impacts and the fragmentation of the laminated windshields.…”
