Forensic reconstructions and ballistic testing requires the use of consistent and repeatable simulants. Synthetic bone has been developed to be mechanically similar to human bone; however, it does not have the same viscoelastic properties. Bone acts as brittle and stiff material and fails instantly under high-energy events such as ballistic impacts. Consequently, bone simulants for use in ballistic testing should show comparable energy deposition to mammalian bones. This study aims to determine if Synbone® flat plates could be a viable proxy for Sus scrofa (domesticus) ribs in ballistic testing with 7.62 × 51 mm Full Metal Jacket ammunition. 5 mm, 6 mm and 12 mm quartered Synbone® plates were embedded into 10% ballistic gelatin and shot using 7.62 mm ammunition. The models were then analysed to compare the Synbone® to a previous Sus Scrofa (domesticus) rib study and focused on energy deposition, the number of fragments within the block, angle of deviation, onset of yaw, the temporary cavity, and the permanent wound channel. No significant difference was seen between the Sus Scrofa (domesticus) and the 5 mm Sybone®. There were significant differences observed between Sus Scrofa (domesticus) ribs and 6 mm Synbone® for the number of fragments, energy deposition and projectile tract diameter, and significant differences seen between Sus scrofa (domesticus) ribs and 12 mm Synbone® for the depth of onset of yaw, energy deposition and projectile tract diameter. This study indicates that the 5 mm Synbone® plate is a suitable proxy for Sus scrofa (domesticus) ribs for use with 7.62 × 51 mm FMJ ammunition in ballistic testing.

法医重建和弹道测试需要使用一致且可重复的模拟物。合成骨已发展为在机械上与人骨相似；然而，它不具有相同的粘弹性。骨头作为脆而坚硬的材料，在高能事件（如弹道冲击）下会立即失效。因此，用于弹道测试的骨骼模拟物应显示出与哺乳动物骨骼相当的能量沉积。本研究旨在确定 Synbone® 平板是否可以成为Sus scrofa（家养）的可行替代品使用 7.62 × 51 毫米全金属外壳弹药进行弹道测试的肋骨。将 5 毫米、6 毫米和 12 毫米四分的 Synbone® 板嵌入 10% 弹道明胶中并使用 7.62 毫米弹药射击。然后对模型进行分析以将 Synbone® 与之前的Sus Scrofa (domesticus)肋骨研究进行比较，并重点关注能量沉积、块内碎片的数量、偏差角度、偏航的开始、临时空腔和永久性伤口渠道。Sus Scrofa (domesticus)和 5 mm Sybone®之间没有显着差异。在Sus Scrofa (domesticus)之间观察到显着差异肋骨和 6 mm Synbone® 的碎片数量、能量沉积和弹道直径，以及Sus scrofa (domesticus)肋骨和 12 mm Synbone® 之间在偏航开始深度、能量沉积和弹道直径方面的显着差异。这项研究表明，5 毫米 Synbone® 板是Sus scrofa（国内）肋骨的合适替代品，可在弹道测试中与 7.62 × 51 毫米 FMJ 弹药一起使用。
