Application of Random Aggregate Model to the Problem of Concrete Penetration

Abstract:

Penetration of concrete targets was simulated based on self-compiled program generating two-dimensional random aggregate model. Random convex polygons were used to simulate the aggregate particles of concrete, HJC model to describe constitutive relations of the aggregates and mortar while concrete targets are subjected to large strains, high pressure and high strain rate. With this model, the Forrestal's penetration test was simulated by ls-dyna software. By comparing the calculated results with the test data, It is shown that random aggregate model can be applied to simulate the dynamic destruction problems of concrete-like materials.
