The ballistic resistance of a combined soft tissue simulant was studied, consisting of gelatine as a simulant for human muscle tissue and tanned cowhide (leather) as a simulant for human skin. The simulant was manufactured by applying cowhide to liquid ballistic gelatine, as the gelatine solidified in its mould. Combining a skin and muscle tissue simulant in this adhered way opens the possibility to produce purpose-built proxies for human body parts in ballistic studies or for forensic shooting incident reconstructions. Ballistic resistance of adhered cowhide - (bonded) to solidifying ballistic gelatine - was compared to that of the same material applied on gelatine blocks in loose condition. Ballistic resistance of tanned cowhide was found to be more consistent in adhered condition. This enhanced consistency is a benefit, increasing reproducibility of results in ballistic studies. Additionally, two ways to assess ballistic resistance of a skin simulant were described and compared. Logistic regression, from a number of measured velocities and associated (non)perforations is recommended for testing ballistic resistance.
研究了一种由明胶模拟人体肌肉组织和鞣制牛皮（皮革）模拟人体皮肤组成的软组织模拟物的弹道阻力。该模拟物是通过将牛皮应用于液态弹道明胶来制造的，因为明胶在其模具中凝固。以这种附着的方式将皮肤和肌肉组织模拟物结合在一起，为弹道研究或法医射击事件重建中人体部位的专用代理物的生产开辟了可能性。附着的牛皮（粘合）到凝固的弹道明胶的弹道阻力与松散状态下应用于明胶块的相同材料的弹道阻力进行了比较。发现鞣制牛皮在附着状态下的弹道阻力更加一致。这种增强的一致性是一种优势，可提高弹道研究结果的可重复性。此外，还描述和比较了两种评估皮肤模拟物弹道阻力的方法。建议使用逻辑回归，根据多个测量速度和相关的（非）穿孔来测试弹道阻力。
