A Detailed Numerical Investigation of Insulated Glass subjected to the Standard Pendulum Test
Structural glazing design must reliably withhold static loads e.g. hand rails loaded by crowds, as well as dynamic loads, e. g. impacting persons or objects. Due to the ideally elastic behavior up to the brittle failure of glass, the ...
