The calculation of the projectilepenetration into target has always been a hot and difficult issue in thescholastic circles. In recent years, a new numerical method, XFEM, has been emerged basedon the conventional finite element method (CFEM), so that the crack propagationproblem has been developed by leaps and bounds. Based on XFEM, the researchfocuses on the crack propagation problem in the process of projectilepenetration into target. In addition, the crack propagation mechanism and itsinfluence of material mechanical properties in the process of projectilepenetration into target are analyzed.

The existence of pores is a very common feature of nature and of human life, but the existence of pores will alter the mechanical properties of the material. Therefore, it is very important to study the impact of different influencing factors on the mechanical properties of porous materials and to use the law of change in mechanical properties of porous materials for our daily lives. The SBFEM (scaled boundary finite element method) method is used in this paper to calculate a large number of random models of porous materials derived from Matlab code. Multiple influencing factors can be present in these random models. Based on the Monte Carlo simulation, after a large number of model calculations were carried out, the results of the calculations were analyzed statistically in order to determine the variation law of the mechanical properties of porous materials. Moreover, this paper gives fitting formulas for the mechanical properties of different materials. This is very useful for researchers estimating the mechanical properties of porous materials in advance.
