Contact analysis of any Shaped Rigid Bodies

This paper presents a method for calculating contact force of any shaped rigid bodies on plane. At each integration time step, the proposed method finds expected contact point on their outlines and then calculates penetration and contact force. This paper is using the continuous analysis method to calculate contact force. To get the accurate expected contact point on their outlines, a new algorithm is developed. Through the comparison with DADS, the accuracy of the proposed algorithm is proved.
