Working Group 3

Post-Fracture Performance
Post-Fracture Performance

WG 3 Chair: Dr Mauro OVEREND

Aims & Objectives

The principal aim of this working group is to advance knowledge on the post-fracture performance of glass. This working group is addressing Priority Area 3 identified by the research network - An integrated design approach incorporating risk analysis and post-fracture mechanics.

Glass is inherently brittle and has a relatively low tensile strength. As a result the overarching design philosophy is to ensure adequate strength and stability for normal actions and to provide safe failure or adequate residual post-fracture capacity thereby minimising the risk of human injury. This fundamental ‘fail-safe’ concept is currently not embedded in the design process, largely due the lack of quantitative methods for assessing the post-fracture performance of glass. This shortcoming leads to a high risk of glass-related human injuries particularly in extreme events. The objectives of the working group are to unify and advance knowledge at two levels:

  • The component level, where structural integrity and residual load-bearing capacity is a function of the visco-elastic interlayer properties, the fragmentation of glass and local delamination effects. 
  • The system level, which extends the fail-safe concept to connections and to the overall performance of the assembly of glass components.
