A MATLAB GUI for the prediction of coefficients of restitution.

The motivation behind a MATLAB GUI to predict the coefficients of restitution is to enhance the fidelity of rigid body simulations. Currently, the common practice is to use the coefficient of restitution as a way to capture numerous factors of damping instead of using a coefficient true to the materials in contact. By switching to a model that predicts the coefficient of restitution as a function of velocity between any two materials, rigid body simulations will be more accurate due to higher fidelity models of the actual physics. Additionally, by packaging this software with a library of materials, all rigid body simulations can be run using consistent properties, eliminating any guesswork and “ballpark” figures. This report will therefore cover the existing code and how it delivers all of the features needed to easily estimate coefficients of restitution.
