One of the last frontiers in structural dynamics is the behavior of buildings under the effects of impact and explosions. Traditionally, this area has been under study by using field testing with high explosives HE. In recent years, however, both the high cost and the well-known lack of precision associated with field HE tests are of great concern. Although valuable for many purposes, data from field tests may not be useful for precise description of complicated structural behavior or in support of development, verification and validation of numerical capabilities. The anticipated decline in funding for RD in fortification science and technology is particularly critical when large scale tests are considered. Due to current limitations in numerical simulation capabilities, RD organizations must rely on expensive tests to provide recommendations on specific problems. If the cost for obtaining such answers cannot be dramatically reduced, it could affect the viability of RD in this critical field of science and technology. This paper examines a promising approach that shows significant potential to overcome this problem, and provides recommendations on how to implement it.
