Abstract

Frictional Contact Problems Involving Large Displacements using B.E.M. A. Lorenzana , J.A. Garrido and I. Prieto & 71 EMail: ali@dali.eis.uva.es Abstract A new algorithm is presented for the boundary element analysis of the static two-dimensional contact problem between elastic solids. The contact constraints are not applied node-on-node (node-pairs technique) but node-on-element, using quadratic shape functions for distributing the geometry, displacements and tractions on each element at the contact zone. Thus, the dis- cretizations performed along the two surfaces in contact do not have to be the same. The solution procedure is based on the updated lagrangian approach and the resulting method is incremental. At least one increment of load must be done for each node changing its boundary condition, the geometry being updated after each increment Additional updatings must be done in order to notice any significa
