This paper describes the process of creating a numerical FEM (finite element method) model of the 5.56 × 45 mm SS109 projectile. The model was used to calculate the temperatures occurring in the projectile materials during the impact on the steel plate at an angle of 45°. The purpose of the investigation is to estimate the ability of a ricocheting projectile to cause ignition. For the same projectile, experimental tests were also carried out under the conditions adopted for the numerical investigation in order to validate the FEM model. During the experiment, temperature was measured with a thermal camera; the phenomenon was also recorded with a colour high-speed camera.
本文描述了创建5.56×45毫米SS109子弹的有限元法（FEM）数值模型的过程。该模型用于计算子弹以45°角撞击钢板时子弹材料中产生的温度。研究目的是评估跳弹引起着火的能力。对于同一颗子弹，还在数值研究采用的条件下进行了实验测试，以验证有限元模型。实验过程中，用热成像仪测量温度；还用彩色高速摄像机记录了该现象。
