Experimental Bench Mark Data for ALEGRA Code Validations
In this study experiments of increasing complexity have been conducted to provide a data base for validating features of the Arbitrary Lagrangian Eulerian Grid for Research Applications (ALEGRA) code over a broad range of strain rates with overlapping diagnostics that encompass multiple responses. This range encompasses strain rates characteristic of shock-wave propagation (107/s) and those chameteristics of structural response (102/s). The tests matrix consists of two experimental series; the first being a simple system test with diagnostics that capture features relevant to both the high strain-rate hydrodynamic response and the low strain-rate structural response of the target. The second series of experiments increased the complexity of tests with the addition of foam to the original simple series. The input conditions are extremely well defined. Velocity interferometers are used to record the high strain-rate response, while the low strain-rate data were collected using strain, carbon and PVDF gauges.
