Background
- Laminated glass (LG) is crucial for safety applications, particularly against explosive threats.
- Understanding the influence of LG cross-section on blast performance is vital for structural integrity.
Purpose Of The Study
- To numerically investigate the effect of laminated glass cross-section on blast performance.
- To evaluate different interlayer materials and configurations for optimal blast resistance.
Main Methods
- Utilized a high-fidelity Arbitrary Lagrangian-Eulerian (ALE3D) multiphysics model to simulate LG behavior under blast loads.
- Verified numerical models against experimental data from existing literature.
- Analyzed various configurations including double and multi-layer glass panels with different polymer interlayers (PVB, EVA, TPU, SG).
Main Results
- SentryGlas® (SG) interlayers demonstrated superior blast resistance compared to PVB, TPU, and EVA.
- EVA and TPU interlayers performed poorly, while hybrid interlayers underperformed due to load-sharing issues.
- Increasing interlayer thickness improved resistance, and specific glass thickness combinations (thick middle, thin outer layers) minimized deflection.
Conclusions
- Interlayer material selection and layup design critically impact the blast performance of laminated glass panels.
- SG interlayers offer significant advantages for blast-resistant applications.
- Optimized glass and interlayer configurations are essential for enhancing the safety and resilience of LG systems.

The design of prismatic beams, structural elements with a uniform cross-section, focuses on ensuring safety and structural integrity under load. The design process begins by determining the allowable stress, either from material properties tables, or by dividing the material's ultimate strength by a safety factor. This safety factor is essential for accommodating uncertainties, and varies depending on the material—timber, steel, or concrete—with each having unique strength and...
Assessing safety in wind-exposed installations is crucial to preventing potential failures. This example explores the calculation and design adjustments needed to mount a circular disc on a building facade, where wind forces are a primary concern. A 4-meter diameter disc was initially designed as an aesthetic feature facing winds at a velocity of 25 meters per second, with an air density of 1.25 kilograms per cubic meter. Given these conditions, the drag force on the disc was determined using...
Brittle materials, including glass, cast iron, and stone, exhibit unique characteristics. They fracture without considerable change in their elongation rate, indicating that their breaking and ultimate strength are equivalent. Such materials also show lower strain levels at the point of rupture. The failure in brittle materials predominantly results from normal stresses, as evidenced by the rupture created along a surface perpendicular to the applied load. These materials do not display...
In the design of a supported timber beam subjected to a distributed load, both the beam's physical dimensions and the timber's characteristics, such as its grade and species, are critical. These factors determine the allowable stress values, which are crucial for calculating the necessary beam depth to ensure structural integrity and safety.
The design begins with analyzing the beam as a free body to identify moments and force balances, thereby determining support reactions. Next, the...
Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.
The factor of safety is another key...
Thin-walled members with non-symmetrical cross-sections are vital to engineering structures, offering material efficiency and structural integrity. However, unsymmetrical loading on these members leads to complex stress distributions, resulting in simultaneous bending and twisting can cause deformation or structural failure. The interaction between bending and twisting requires detailed analysis to ensure structural resilience.
The concept of the shear center is crucial in countering the...
