LS-DYNA TUTORIAL 13: Reinforced Concrete and Wrecking Ball

I’ve been requested by many from Civil Engineering background to do a tutorial. So here it goes. I must highlight that I am actually from Mechanical Engineering, so if I said some of the terms wrong, or some of the values doesn’t make sense, feel free to laugh at me. But after you do so, please correct me in the comments! In this tutorial, a reinforced concrete slab is subjected impact by wrecking ball. The wrecking ball is dropped from a horizontal position (I know this is not practical, but this tutorial is only for learning purposes). The concrete is reinforced with steel bars, modelled as beam elements. The interaction between reinforcement and the concrete is modelling with CONSTRAINED_LAGRANGE_IN_SOLID coupling. Two material models for the concrete were used in this video, first, MAT159_CSCM_CONCRETE and then MAT084/85_WINFRITH_CONCRETE. The former has the option of defining the plastic strain if element erosion is required. This material model is a good option when modelling concretes
