A stabilized finite element formulation of non-smooth contact
The computational modeling of many engineering problems using the Finite Element method involves the modeling of two or more bodies that meet through an interface. The interface can be physical, as in multi-physics and contact problems, or purely numerical, as in the coupling of non-conforming meshes. The most critical part of the modeling process is to ensure geometric compatibility and a comp...
متن کاملFinite 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 کاملDiscrete Element Simulation and the Contact Problem
This paper addresses the problem of contact detection in discrete element multibody dynamic simulations. This paper presents an overview of the problem and a detail description of a new object representation scheme called the discrete function representation (DFR). This representation is designed to reduce the computational cost of both contact detection and the more diicult problem of contact ...
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 ...
متن کاملAnalysis of the Contact Area of Smooth and Rough Surfaces in Contact with Sphere Indenter Using Finite Element Method
This paper analyzes the contact area of the contact between a deformable rough surface (smooth and rough) and a hard smooth sphere indenter using finite element method. A method was introduced to generate a three dimensional rough surfaces using Computer Aided Design (CAD) software. The rough surface model was developed based on the surface measurement data, while the smooth surface model was g...
