This study aims ultimately to quantify the force needed to penetrate human tissue. The results will reduce the subjectivity of expert opinion in stabbing incidents. They will also aid clinicians in assessing the severity of injury and help prevent the unnecessary deaths which can occur when this is not fully appreciated. Tensile tests were performed to identify suitable skin simulants with synthetic chamois and pigskin as candidate materials. Quasi-static penetration experiments were also performed in which a knife blade penetrated a skin simulant target. Pigskin was found to be much stronger than chamois under tensile load yet the puncture resistance was almost identical for the two materials.
本研究最终旨在量化穿透人体组织所需的力量。研究结果将减少刺伤事件中专家意见的主观性。它们还将帮助临床医生评估损伤的严重程度，并有助于防止在未充分认识到这一点时可能发生的不必要死亡。进行了拉伸试验，以确定以合成麂皮和猪皮为候选材料的合适皮肤模拟物。还进行了准静态穿透实验，其中刀片穿透皮肤模拟物目标。结果发现，在拉伸载荷下猪皮比麂皮结实得多，但两种材料的抗穿刺性几乎相同。
