Holistic post-breakage characterization for optimized safe design of glass under multi-hazard
HOPgLAz explores with multi-scale extended experiments and parametric numerical analyses the post-breakage performance and the post-breakage mechanical parameters of laminated glass (LG) components for buildings that are variably composed and loaded, including ageing effects. The goal is to provide engineering knowledge advancement and to derive holistic damage characterization for LG components, in support of an optimal design of novel structures and retrofit / maintenance of in-service structures.
Objectives
HOPgLAz will develop a new holistic formulation for the post-breakage performance assessment of LG elements with partial damage, under different section properties and material compositions, loading features, ageing condition. A formulation will be proposed to quantify the mechanical parameters of fractured LG sections, and safely described their post-fracture residual capacity. This will provide strong advancement in research knowledge, as well as powerful tools on the side of mechanical design and fulfillment of fail-safe design principles
Research methodology and timelining
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.
