Soft materials, like skin, behave differently than hard materials when punctured. They provide an unstable resistance that is more difficult to describe and hence predict. Researchers at the University of British Columbia have answered the previously unsolved question of how the mechanics of piercing works on soft materials by studying solutions from the natural world, and have created a mechanical theory that finally predicts the critical force necessary for needle insertion.
