Simulation of Reactive Fluoropolymer-Based Material Penetrator

Year: 2024

Type: article

Abstract: 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.
