Model of high-speed interaction in the «damaging element — obstacle» system of loaming ammunition

The article describes a model of high-speed interaction in the «striking element — barrier» system of a barrage munition, which allows modeling and analyzing the dynamics and mechanisms of barrier destruction when interacting with various types of striking elements. The model is based on the finite element method using a time-evolving adaptive mesh thickening algorithm and takes into account various mechanisms of fracture of the barrier material, such as brittle fracture, plastic flow and shear localization. The study demonstrates the accuracy and effectiveness of the model and shows its ability to predict the mechanisms of barrier failure and kinematic fields of deformations and stresses. The model can be used to analyze various scenarios of high-speed interaction and optimize the designs of weapons and obstacles. The developed model is important for understanding the mechanisms of destruction during high-speed interaction.
