A Fast-Running Finite Element Based Method for Evaluating the Blast Performance of Laminated Insulated Glazing

The current state of practice in the design and assessment of Insulated Glazing Units to resist blast loading utilizes calculation methods to estimate the performance. The most prevalent methods used for calculating the window’s performance have been developed from a single degree of freedom (SDOF) approach. This paper presents an alternative, finite element based, approach to analyzing the blast performance of laminated insulated glazing units. The modeling approach is described for each of the primary components represented in the analysis and the results of an indicative model are compared against an equivalent analysis calculated using SDOF methods.Copyright © 2008 by ASME
