Finite element analysis of nonsmooth contact
This work develops robust contact algorithms capable of dealing with complex contact situations involving several bodies with corners. Amongst the mathematical tools we bring to bear on the problem is nonsmooth analysis, following [14]. We speci cally address contact geometries for which both the use of normals and gap functions have difculties and therefore precludes the application of most co...
متن کاملFinite Element Interpolation of Nonsmooth Functions
In this paper, we propose a modified Lagrange type interpolation operator to approximate functions in Sobolev spaces by continuous piecewise polynomials. In order to define interpolators for "rough" functions and to preserve piecewise polynomial boundary conditions, the approximated functions are averaged appropriately either on dor (d 1 )-simplices to generate nodal values for the interpolatio...
متن کاملmulti layered finite element analysis of graded coatings in frictional rolling contact
a plain strain analysis of frictional rolling contact on an elastic graded coating is presented in this paper. finite element method is applied to gain an understanding of the stresses and contact zone properties caused during rolling contact. the effects of friction, material stiffness ratio and coating thickness on stresses in contact zone and coating/substrate interface are studied. shear mo...
متن کاملAn Error Estimator for Adaptive Frictionless Contact Finite Element Analysis
The derivation of an a posteriori error estimator for frictionless contact problems under the hypotheses of linear elastic behavior and infinitesimal deformation is presented. The approximated solution of this problem is obtained by using the Finite Element Method. A Penalization or Augmented-Lagrangian technique is used to deal with the unilateral boundary condition over the contact boundary. ...
متن کاملFinite Element Modeling of Contact Problems
Contact is the principal way load is transferred to a body. The study of stresses and deformations arising due to contact interaction of solid bodies is thus of paramount importance in many engineering applications. In this work, problems involving contact interactions are investigated using finite element modeling. In the first part, a new augmented Lagrangian multiplier method is implemented ...
