Dynamic Contact Analysis Satisfying All the Compatibility Conditions on the Contact Surface

접촉면에서 모든 적합조건을 만족시키는 동적인 접촉현상의 해법

For the numerical solution of frictional dynamic contact problems, correct contact points and displacements are determined by iteratively reducing the displacement error vector monotonically toward zero And spurious oscillations are prevented from the solution by enforcing the velocity and acceleration compatibilities of the contact points with the corresponding error vectors. Numerical simulations are conducted to demonstrate the accuracy of the solution and the necessity of the velocity and acceleration compatibilities on the contact surface.
