Large Displacement Dynamic Analysis with Frictional Contact by Linear Complementarity Formulation

선형 상보성 수식화를 이용한 마찰 접촉 대변형 동역학 문제의 해석

For a large deformation nonlinear dynamic analysis of two-dimensional frictional contact, the linear complementarity formulation combined with a linearization is used. The solution procedure is based on the total Lagrangian formulation with a predictor and corrector scheme. For contact searching, a hierarchical scheme with a circular territory is used. A second-order approximation of displacements is used to detect impact time and position. The formulation is illustrated by means of numerical examples.
