Resumen

This paper presents the results of a wide experimental of ballistic tests against FV535 plates at temperatures from room to 700ºC. Those tests have been done using a light gas gun shooting round balls up to 800m/s. Residual velocity curves and the ballistic limit at different temperatures has been obtained. To check if the material model obtained from the Hopkinson bar tests reproduces the behavior of the material, the impact tests on FV535 plates are compared with numerical simulations. In those simulations the residual velocity curves have been compared with the experimental ones, introducing the Johnson-Cook fracture model in LSDYNA explicit code. The results shows that the model obtained reproduces very well the residual velocity curves. Taking a closer look at the impacted plates, and comparing the final geometry against the numerical simulations, the experimental and numerical geometries of the plates are almost identical. The special nature of these impact tests has been crucial to verify the Johnson-Cook fracture model
