Abstract
The work concerns the analysis of a material solution on an aramid laminate reinforced with additional composite layers loaded with ballistic impact from the 7.62 mm M43 Full Metal Jacket (FMJ). The aim of the study is to identify alternative material systems to the reference 4 mm thick Armox A500T armored steel solution. The research was carried out using the finite element method with the application of the ABAQUS program. The optimal solutions for individual material systems were generated based on numerical analyses, thereby classifying them according to the mass-efficiency criterion. The numerical results obtained were validated in a ballistic experiment on samples made according to the methodology adopted for modeling. The range of absorbed energy and residual energy was determined for material systems based on the assumptions of the Recht-Ipson model.
这项工作涉及分析芳纶层压板上的材料溶液，该层压板带有附加的复合材料层，这些复合材料层受到7.62 mm M43全金属护套(FMJ)的弹道冲击。该研究的目的是确定替代4毫米厚Armox A500T装甲钢解决方案的材料系统。采用有限元方法，应用ABAQUS程序进行研究。在数值分析的基础上，生成了各个材料系统的最优解，从而根据质量效率准则对其进行分类。根据所采用的建模方法对样品进行了弹道试验，验证了数值计算结果。根据Recht-Ipson模型的假设，确定了材料体系的吸收能和剩余能的范围。
