Abstract When a projectile penetrates a multi-layer target, it will cause damage with somewhat different degree to the target. The degree of damage is related to the initial velocity and the fragile characteristics of the projectile. Using the method of FEM-SPH coupling simulation, penetrating experiments were numerically simulated under the same working conditions. In order to quantify the damage degree of the target plate, the target plate mass loss rate and the target plate area increase rate were used as the indeces to evaluate the damage degree, and the index numbers of the corresponding target plate were solved.Then, the two indeces were superimposed to offer a failure index to evaluate the damage degree of the target plate. The comparison of the failure indeces inspected shows that the breakage effect of the fragile projectile is more obvious than that of the ordinary projectile on the target plate, and the higher the velocity, the greater the damage degree. The numerical simulation results are basically the same as the experimental ones.

Key words： fragile projectile, spaced target plate, numerical simulation.
