Title Establishment of a VISAR Measurement System for Material Model Validation in DSTO.

Abstract This report describes the establishment of a velocity interferometer measurement system, VISAR, capability in DSTO for recording high-temporal resolution velocity data in high-velocity impact experiments. This data is critical for model validation, material and warhead performance characterisation and effects studies. The present report describes preliminary plane impact tests used to establish the VISAR capability, and evaluates the methodological resolution issues relating to the experimental set-up. The set- up misalignment effects observed on the VISAR records have been numerically analysed using the CTH hydrocode and will be taken into consideration in future test programs.
