Abstract
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.
