Develop High Speed Blast Impact Detector System (HVBIDS)

Acellent will develop High Speed Blast Impact Detector System-HVBIDS. The system will integrate high frequency sampling modules in the passive monitoring technique to respond to an impact event for generation of wave fields that would become the input of stress-strain reconstruction input in advanced finite element modeling process and perform benchmark study on the responding times. Acellent will develop real time calculation algorithm for the measurement of dynamic strain and stress caused by the impact. The main goal of HV-BIDS is for monitoring high speed blast impact event on the war fighter platforms in situ. HV-BIDS will provide: (1) Real time in-the-field stress measurements under blast loading conditions, (2) The sensor network will survive under blast pressure waves and complex geometrical deformation during or after the impact event, (3) The system can provide immediate measurement during the elastic-plastic transition on the surface of the structure, and (4) The system can provide input for validation of the 3D FEM and material deformation models.
