Abstract

Contact problems involving large deformation of curved beams are difficult to analyze due to uncertainty of contact positions and strong nonlinearity. A nonlinear large-deformation model of curved beams is formulated in arc-length coordinates. A new adaptive differential quadrature element method (ADQEM) is proposed to predict contact positions of a curved beam with a finite number of contact points, where a dragging method and continuity conditions are combined to determine the contact positions. Simulation results show that the ADQEM greatly improves efficiency and accuracy of the large-deformation contact problem of the curved beam. The number of iterations in the present method does not greatly increase with the number of contact points.
