Numerical Simulation on Penetration Properties of Concrete Based on Random Particle Model

As an important building material, concrete is widely used in military and civil areas for its superiorities, such as civil engineering, hydraulic engineering, protection engineering and so on. It is necessary to research its dynamic mechanical properties under strong shock loading. The concrete is considered as a composite material which is made of aggregate particles and cement paste from micromechanical angle. This paper uses random function to establish random particle model and simulates dynamic mechanical responses of concrete under strong shock loading based on random particle model using ANSYS/LS-DYNA.
