Abstract:

The last eight years have seen increasing interest in blast protection. The result has often been an overreaction, such as the unnecessary closing of Pennsylvania Avenue in front of the White House. However, rational engineering design can produce a better situation, providing adequate protection while preserving American freedom of movement. Often designs involve laminated tempered glass (bulletproof glass). There is a substantial record of laminated tempered glass testing in blast experiments. This lecture will address design considerations based on test data.
