Abstract
In this report, the Damage Boundary Theory and related analysis using the Shock Response Spectrum have been investigated. In particular, physics-based computer modeling and simulation using the MSC/NASTRAN code has been performed for the case of a rotational drop test model. Application of the Damage Boundary Theory and subsequent analysis using the Shock Response Spectrum is useful in understanding the isolation level of packaging systems. The results of the computer simulations show the effects of the flexibility in the equipment and nonlinearity of the shock mounts analyzed in this research. The data from these simulations have been compared with the shock test specification, MIL-STD-810.
