Abstract Soda-lime glass is a brittle and transparent material that is known for its rapid and sudden fracture behavior. Since the use of soda-lime glass in protective structures is increasing, a more comprehensive understanding of this challenging fracture behavior is needed. The aim of this work is to investigate how the load level affects the crack propagation and to generate an experimental database for L-shaped soda-lime glass specimens with curved crack paths. We designed a repeatable testing procedure which reveals the crack propagation behavior of the specimen and allows for extraction of valuable experimental data. A total of 20 experiments were conducted on L-shaped soda-lime glass specimens subjected to a controlled displacement. High-speed cameras were used to monitor the crack propagation and the high-speed footage was post-processed using an in-house procedure to extract the crack path and speed data. We found a positive correlation between the measured initial crack speed and the load level at fracture. The crack propagation path followed four distinct stages and was also affected by the load level at fracture. With this experimental database, we have provided important insight into how the load level affects the crack propagation in soda-lime glass.

Abstract Recently, the numerical simulation of the residual load-bearing capacity of laminated glass (LG) is an often discussed but not sufficiently solved problem in structural glass design yet. According to CEN/TS 19100:2021 (2021a), and CEN/TS 19100:2021 (2021b), the design in the Post Fracture Limit State (PFLS) is possible experimentally and numerically. Experimental verification requires large-scale component tests, which are often costly and time-consuming. The resource-saving numerical approach is to be preferred. However, at the moment, there is no sound numerical model capable of representing the complex load-bearing mechanisms of broken laminated glass (LG) in civil engineering practice. These mechanisms are the finite-strain response of the interlayer, the contact between glass fragments or shards themselves, and the bond between glass and interlayer. Delamination governs the latter one mainly. This work focuses on the experimental, mechanical, and numerical characterization of the finite-strain behavior of polymeric laminated glass interlayers at long load durations by the example of standard single-layer Polyvinylbutyral (PVB). Based on that, it introduces an approach enabling the simplified numerical simulation of LSG interlayers. The considerations rely on experiments and thermodynamic considerations.
