•Blast response of laminated glass (LG) has been numerically investigated.•Influence of interlayer thickness and Young’s modulus (E) were studied.•Constant adhesion between glass and interlayer was maintained.•Design target should be critical interlayer thickness or Young’s Modulus (E).•The safer failure mode enhances energy absorption and reduces support reaction.
This paper investigates the influence of interlayer properties on the blast performance of laminated glass (LG) panels. A parametric study is carried out by varying the thickness and Young’s modulus (E) of the interlayer under two different blast loads. Results indicate the existence of a critical interlayer thickness (or E) that causes the onset of interlayer failure. This should be achieved in the design to enhance energy absorption, reduce support reactions and initiate a safer failure mode. Present findings provide information to achieve such design targets and enable safe and efficient performance of LGs under credible blast loads.
