Other Title
A review of concrete modelling and hydrocode applications
Abstract
The RHT concrete model has been developed at Ernst-Mach-Institut 10 years ago. It is combines detailed trixial strength descriptions at moderated strain rates before and beyond damage with non-linear equation of state properties for strong shock waves. The model is readily available to all users of the commercial hydrocode AUTODYN and continuously supported since the year 2000. Over the last decade it has found numerous worldwide applications reflected in publications. They deal with dynamic load cases such as projectile and shaped charge penetration, contact detonation, internal and external blast loading. The key aspects during the development at EMI and the validation, discussion and extended use of the model by various research and development organizations are reviewed in the following.
