Impact Resistance of Concrete Structures

الملخص EN

We present simulations on the resistance of concrete structures due to impact loading.

Therefore, a mesh-free method is exploited in combination with a viscous damage model that accounts for strain rate effects and high pressures that commonly occur in those events.

In contrast to many other studies in the literature, we account for uncertainties in the material parameters by subjecting them to a probability distribution function.

Furthermore, we also consider the geometric correlation inside the concrete and show that this geometric correlation has a minor influence on the predicted results.

All numerical results are compared to the impact experiments performed by Hanchak and coworkers as well as our own impact experiments.
