简介 弹道明胶是最常见的组织模拟物，用于再现射弹穿透肌肉的情况，但支持其使用的公开数据主要基于子弹，尽管爆炸碎片是当前作战部署中士兵受伤的最常见原因。已发表的使用动物和人造皮肤和肌肉组织替代物的弹道测试也缺乏方法标准化，因此目前与人体组织的比较有限。方法将三块圆柱形北约标准碎片模拟射弹（FSP）发射到20％弹道明胶和被杀死的山羊的后大腿上。将皮肤穿孔所需的阈值 (V-th) 和 V-50 速度以及进入肌肉的渗透深度 (DoP) 与明胶进行比较。在明胶和山羊之间比较 DoP 与速度的线性回归线的截距和梯度，显着性定义为 p
Introduction Ballistic gelatin is the most common tissue simulant used to reproduce the penetration of projectiles into muscle but published data to support its use are primarily based on bullets, despite explosive fragments being the most common cause of injury to soldiers on current operational deployments. Published ballistic tests using animal and artificial skin and muscle tissue surrogates also lack standardisation in methodology such that limited comparisons with that of human tissues can currently be made.Method Three masses of cylindrical NATO standardised fragment simulating projectiles (FSPs) were fired at 20% ballistic gelatin and the hind thighs of a killed goat. Threshold (V-th) and V-50 velocities required for skin perforation and depth of penetration (DoP) into muscle were compared with gelatin. The intercept and gradient of the linear regression lines for DoP versus velocity were compared between gelatin and goat with significance defined as p
