Extended two-body problem for rotating rigid bodies
Ho, Alex; Wold, Margrethe; Conway, John Thomas; Poursina, Mohammad (Peer reviewed; Journal article, 2021)A new technique that utilizes surface integrals to find the force, torque and potential energy between two non-spherical, rigid bodies is presented. The method is relatively fast, and allows us to solve the full rigid ... -
Optimal damping coefficient for a class of continuous contact models
Poursina, Mohammad; Nikravesh, Parviz E. (Peer reviewed; Journal article, 2020)In this study, we develop an analytical formula to approximate the damping coefficient as a function of the coefficient of restitution for a class of continuous contact models. The contact force is generated by a logical ...
