Ballistic gelatin as simulant of the human body and organs is a support in forensics. After having obtained very good results for a new gelatin-based composite in terms of physicochemical and rheological properties, this study focused on this material's mechanical behavior during stabbing and shooting versus bovine and porcine organs and standard ballistic gelatin. The hybrid gelatin has a predominantly elastic behavior at 23°C, whereas the elastic modulus becomes practically constant in the 10-0.1 Hz frequency range. In terms of stabbing behavior, the small variations obtained between porcine organs and surrogate are below 5%, the perforation indicating a good similarity. From the ballistic test results using 10 × 28T rubber balls, it has been seen that the hybrid ballistic gelatin conducts to more reliable and reproducible values of perforation/penetration versus standard gelatin, making from it a real candidate for use in forensic tests.
作为人体和器官模拟物的弹道明胶在法医学中起到辅助作用。在一种新型明胶基复合材料的物理化学和流变学性质方面取得非常好的结果之后，本研究聚焦于这种材料在刺伤和枪击过程中相对于牛和猪的器官以及标准弹道明胶的力学行为。这种混合明胶在23°C时主要表现出弹性行为，而弹性模量在10 - 0.1 Hz频率范围内实际上变得恒定。在刺伤行为方面，猪器官和替代物之间获得的微小差异低于5%，穿孔情况表明具有良好的相似性。从使用10×28T橡胶球的弹道测试结果可以看出，与标准明胶相比，这种混合弹道明胶能得出更可靠且可重复的穿孔/穿透值，使其成为法医测试中真正的可用候选材料。
