Description | A simple biomechanical model of a vertebrate lower jaw (fish mainly, but other jaws can be analyzed). Data on jaw dimensions and muscle features are required. The software application simulates contraction of two muscles using the Hill equation to simulate muscle force and velocity as the jaw closes. Various parameters such as bite force, work and power are provided as output. |
