Experimental analysis of freely-hanging laminated glass subjected to blast

Popis výsledku v původním jazyce

This study aims to experimentally test the behaviour of laminated glass when subjected to blast loading from a close-proximity explosion. The main motivation is to conduct an experiment, that would serve as a basis for future numerical modelling of the behaviour, to study the changes when compared to other types of loading. Therefore, the main goal is to test the experimental setup, which must be as simple as possible and ideally without the problematic boundary conditions, as those would be difficult to accurately describe. The presented approach uses square laminated glass specimens made of ordinary float glass and polymer interlayer. The specimens are held by steel ropes to allow their motion in the axis of the applied blast load, which provides a stress-free boundary condition. The explosive is suspended in front of the specimen. This study shows that the approach is suitable for this type of testing and it should provide the necessary data for further studies. However, relatively large explosive weights must be used to cause damage to the specimens and finer steps of increased weights must be used to study the progressive failure of laminated glass.
