Meshfree simulation of concrete structures and impact loading

•Uncertainty analysis determining effects of material parameters on impact resistance of concrete.•Determining the importance of physical effects on impact resistance of concrete.•Computational analysis of impact resistance with meshfree method.

The impact resistance of concrete structures is of major importance in engineering application. Computational methods are increasingly used for such types of applications but face difficulties due to the complex physical behaviour involving large deformations and large strains. Meshfree methods seem ideally suited to deal with these types of problems. In this manuscript, we present stochastic simulations based on the element-free Galerkin method to predict upper and lower bounds of the impact resistance of concrete structures. We account for stochastic distribution of material parameters and validate our results with benchmark experiments conducted by the group of Hanchak.
