Abstract
A system, method and software product to simulate guided cable contacts is disclosed. The guided cable contact includes a slave node and an associated beam. A normal vector is established between the slave node's projection point and the slave node. Each of the slave node and two end nodes of the beam has three translational degrees-of-freedom. A spring is placed between the slave node's projection point and the slave node. The spring constant is assigned such that the spring is substantially stiffer than that of the beam. The guided cable contact stiffness matrix is then calculated using the spring constant, the normal vector, the length of the beam, and the distance between the first end node of the beam and the projection point. According to one aspect, the guided cable contact may be used for modeling human spinal column.
