【摘要】Since computers and software have spread into all fields of industry, extensive efforts are currently made in order to improve the safety by applying certain numerical solutions. For many engineering problems involving shock and impact, there is no single ideal numerical method that can reproduce the various regimes of a problem. This paper presents a set of numerical simulations of ballistic tests, which analyze the effects of soda lime glass laminates, familiarly known as transparent armor. Transparent armor is one of the most critical components in the protection of light armored vehicles. The goal is to find an appropriate solver technique for simulating brittle materials and thereby improve bullet-proof glass to meet current challenges. To have the correct material model available is not enough. In this work, the main solver technologies are compared to create a perfect simulation model for soda lime glass laminates. The calculation should match ballistic trials and be used as the basis for further studies. In view of the complexity of penetration processes, it is not surprising that the bulk of work in this area is experimental in nature. Terminal ballistic test techniques, aside from routine proof tests, vary mainly in the degree of instrumentation provided and hence the amount of data retrieved. Here, the ballistic trials and the methods of analysis are discussed in detail. The numerical simulations are performed with the nonlinear dynamic analysis computer code ANSYS AUTODYN.
