Implementation of dynamic strength models into 2D hydrocodes: Applications for atmospheric breakup and impact cratering

A statistical model of a tensile strength is implemented into the SALE-2D hydrocode. The well-tested 2D code has been modified to handle multi-material problems and strength effects. The key element of the model is the Grady-Kipp-Melosh kinetic model of tensile strength, adopted to hydrocode calcula...

Description
Summary:A statistical model of a tensile strength is implemented into the SALE-2D hydrocode. The well-tested 2D code has been modified to handle multi-material problems and strength effects. The key element of the model is the Grady-Kipp-Melosh kinetic model of tensile strength, adopted to hydrocode calculations. The resulting numerical algorithm allows to estimate general features of the atmospheric breakup of meteoroids and fracturing around impact craters.
