Validation of the Kerley Soil Model in CTH

Abstract

Recently Kerley has developed a soil model suitable for implementation in Eulerian hydrocodes. The model has been installed into CTH [1]. While basic features of the model suggest it may be suitable for modeling ground shock and cratering problems, it has not been extensively validated. As such, in order to provide more confidence in the use the model, a series of calculations was conducted to compare Kerley’s model to the Hybrid Elastic-Plastic (HEP) model.
