Abstract
In this work a constitutive relation for ice at high strain rates and an algorithm for its numerical integra tion are developed. This model is based on the Drucker Prager plasticity criteria, which allows a different behavior in tension and in compression. In addition a failure criteria, based on pressure cut offs, is imple mented to describe the ice damage. In order to validate the constitutive model, numerical simulations were compared with experimental results, in which ice cylinders were impacted against a steel plate, allowing the measurement of the contact load. Three different numerical solvers are used in order to ana lyze its performance to appropriately modeling the ice behavior.
