Contact Analysis Complexities In the previous we consider pseudo-static contact conditions In dynamic analysis: Body forces include inertial force effects and the kinematic interface conditions must be satisfied at all instances of time, requiring displacement, velocity and acceleration compatibility between the contacting bodies. The time integrations schemes (ex. trapezoidal rule) do not automatically satisfy compatibility which therefore has to be imposed separately on the step by step solution Various algorithms have been proposed to solve contact problems in Finite Element analysis.
