摘要
In this study, the ricochet phenomenon of concrete debris impacting on sand is investigated by both experiments and numerical simulations. Three types of debris, including 50 mm empty set concrete spheres, 60 mm and 100 mm chamfered concrete cubes, are employed in the tests. The relationship between the debris impact responses and the incident condition is studied. A numerical modelling is established to simulate the impact of the three types of debris against sand. A parametric study based on the numerical modelling is carried out to study the influence of the sand internal friction angle on the debris impact responses.
