BOUNDARY ELEMENT METHOD FOR MOVING AND ROLLING CONTACT OF 2D ELASTIC BODIES WITH DEFECTS

【摘要】 <正> A scheme of boundary element method for moving contact of two-dimensional elastic bodies using conforming discretization is presented.Both thedisplacement and the traction boundary conditions are satisfied on the contactingregion in the sense of discretization.An algorithm to deal with the moving of thecontact boundary on a larger possible contact region is presented.The algorithm isgeneralized to rolling contact problem as well.Some numerical examples of movingand rolling contact of 2D elastic bodies with or without friction,including the bodieswith a hole-type defect,are given to show the effectiveness and the accuracy of thepresented schemes.更多还原
