Laminated Glass under Blast Loading
Research Guide
What is Laminated Glass under Blast Loading?
Laminated glass under blast loading analyzes the dynamic response, interlayer shear transfer, and fragment retention in PVB-laminated glass panels subjected to explosive pressures.
Researchers employ high-speed testing, numerical simulations, and single degree of freedom models to predict glass fracture and interlayer performance (Morison, 2010; 58 citations). Key studies validate visco-hyperelastic interlayer models against blast experiments (Larcher et al., 2016; 77 citations). Over 20 papers since 2006 focus on PVB and ionomer interlayers for blast mitigation.
Why It Matters
Blast-resistant laminated glazing reduces fragment hazards in military bases and urban structures against terrorist explosions (Morison, 2010). Numerical models enable facade design standardization, improving safety in high-risk environments (Larcher et al., 2016). Bedon et al. (2018; 185 citations) highlight trends in structural glass facades under extreme loads, informing Eurocode updates for blast protection.
Key Research Challenges
Viscoelastic Parameter Identification
Accurate material models for PVB interlayers require dynamic testing across strain rates, as static data fails under blast impulses. Kraus et al. (2017; 66 citations) propose identification methods for visco-hyperelastic models. Validation against high-speed experiments remains inconsistent (Hána et al., 2019; 40 citations).
Fragment Retention Prediction
Interlayer shear transfer post-glass fracture determines debris trajectories and human injury risk. Morison (2010; 58 citations) derives SDOF coefficients but notes variability in real blasts. Chen et al. (2020; 34 citations) show framed PVB glass limits retention under peak pressures.
Numerical Model Validation
Finite element simulations struggle with rate-dependent interlayer behavior and air-blast coupling. Wei et al. (2006; 42 citations) analyze stress waves but lack full-scale validation. Bedon et al. (2018; 185 citations) identify gaps in existing research for facade-scale predictions.
