HOPgLAz will span over 60 months, with 9 Working Packages (WP). The activities will include multi-scale experiments and extended Finite Element numerical simulations. Most of the activities will be carried out at HI, while additional experiments will be necessarily performed at specialized laboratories, as well as at Elettra Sincrotrone (TS) for damage characterization on small-scale samples based on synchrotron radiation.
More in detail
WP1: Administrative & financial management, plus regular PI communication with administrative office
WP2: Literature research, definition of experimental setup features, selection of structural glass prototypes (cross-section features, materials, loading time and amplitude), and detection of real structures in Italy for possible field NDT experimental analyses
WP3: laboratory experiments on small-scale specimens (HI) for the estimation of mechanical parameters in the post-breakage stage. This will include a set of specimens subjected to various loading rates (quasi-static towards impact, cyclic) and interlayer properties. Basic laboratory characterization will be derived from 4 point bending setup. Traditional measures (stress, strain) will be implemented by wifi accelerometers and laser sensors, to correlate the overall parameters. Accelerometer measures will be post-processed as from dynamic identification techniques (OMA), to capture equivalent mechanical parameters for damaged glass.
WP3BIS: full-size experiments for LG samples and prototypes subjected to various damage configurations, loading protocols and ageing conditions.
WP3TER: in parallel, the post-breakage performance of similar small-scale specimens will be investigated with the support of synchrotron radiation at Elettra Sincrotrone. The availability of small-scale samples corresponding for composition and damage to laboratory experiments will allow to find possible correlation with WP3 and WP3BIS.
WP4: FE numerical analysis of small- & full-scale specimens. Based on experimental observations FE models and simulations under different loading and boundary conditions will be used to derive and validate simple modelling procedures in which glass fracture in LG elements can be efficiently and realistically described.
WP5: Post-processing and elaboration of experimental data (small- and full-scale), as well as FE numerical outcomes.
WP6: Formulation of holistic analytical model and derivation of practical design rules, guide lines, recommendations to support the analysis and design of variably loaded and restrained structural glass elements in the post-breakage stage.
WP7: Dissemination of results, throughout (webinars) and at HOPgLAz conclusion (Final Workshop). Partial and final results will be shared with the scientific community, with stakeholders, etc.
