Abstract

The paper simulated numerically the process of wind-blown sand flow impact-induced erosion of cement-mortar block. The concept of wind erosive critical pressure was put forward. Furthermore, the calculation formula of the impact pressure of sand grains, the attenuation equation of elastic modulus and the calculation formula of sand impact times occurred are deduced when the elastic modulus is known, and the minimum elastic modulus value of wind erosion is deduced.
