Abstract

ABSTRACT: This proposal describes an innovative approach to meeting AFRL s goals of upgrading MEVA to address limitations in its current FRM simulation tools in order to allow it to accurately assess embedded detonations of small munitions in civil construction. The approach makes use of WAI s coupled NLFlex/VCFD software for the HFPB computational component of this effort and leverages WAI s wide ranging experience in using HFPB modeling to simulate the response of the full range of structural construction types to threats of interest. It also relies on WAI s experience in developing innovative FRM tools for characterizing blast effects on concrete components including breach size and secondary debris and familiarity with the MEVA software. BENEFIT: Upon successful completion of the Phase 1 effort, WAI will have demonstrated the practicality of using the NLFlex/VCFD software to simulate complex embedded detonations problems of interest to AFRL and demonstrated its ability to provide the necessary response measures from an FRM generated from the HFPB cases. Once proven, this end-to-end approach to generating FRM response modules in MEVA will be adapted to the full range of construction and load types of interest to AFRL in a follow-on Phase II effort. The primary market for the embedded detonation blast response modules that will be developed under this project would primarily be DHS and DOD organizations in the U.S.(such as DTRA).
