The dorsal scale of Laudakinstoliczkanain desert has good performance of erosion-resistance because it is composed of protein "soft" layer and the covering of the cuticle "hard" layer. In this paper, we simplify it to a layered structure called a bionic layered structure(BLS). Based on it, a numerical model for a single particle to impact BLS is established for simulating the impact process. Analysis results shows that BLS can effectively weaken the incident stress wave amplitude, to prevent the failure or damage of the whole structure.
