It is very important to solve the numerical simulation of fluoropolymer-based reactive materials in the process of engineering design. Although custom development techniques are rapidly being applied to numerical simulation problems of reactive materials, they are inconvenient for engineering designers to implement. This paper presents several simulation methods for fluoropolymer-based reactive materials that can be implemented on commercial software platforms. Comparative analyses were conducted on the intrusion-explosion simulation based on a segmented simulation, a simulation based on the Lee-Tarver EOS, and a simulation of impact response models based on the MPM-SICR algorithm. Additionally, the similarities between these methods and experiments were compared. The results show that the impact response model simulation method based on the MPM-SICR algorithm has certain advantages in describing the impact detonation characteristics of reactive materials. The research findings can provide design assistance and a reference for the application design and damage assessment of fluoropolymer-based reactive material penetrators.
在工程设计过程中,解决含氟聚合物基反应材料的数值模拟问题非常重要。尽管定制开发技术正迅速应用于反应材料的数值模拟问题,但工程设计人员实施起来并不方便。本文提出了几种可在商业软件平台上实现的含氟聚合物基反应材料模拟方法。对基于分段模拟的侵入-爆炸模拟、基于Lee-Tarver状态方程的模拟以及基于MPM-SICR算法的冲击响应模型模拟进行了对比分析。此外,还比较了这些方法与实验之间的相似性。结果表明,基于MPM-SICR算法的冲击响应模型模拟方法在描述反应材料的冲击起爆特性方面具有一定优势。研究结果可为含氟聚合物基反应材料侵彻体的应用设计和损伤评估提供设计辅助和参考。
