... and the contact mechanisms have a strong influence on the dynamics of the joint. The analytical model shows that a disassembly force is always lower than an assembly force. In addition, the contact pressure along the interface is heterogeneously influenced by the geometry and changes significantly over the life...

... in order to describe contact between the interfaces. The numerical method used here leads to the successive solution of quadratic optimization problems. Finally, structures with different fractal interfaces are analyzed in order to obtain results for the relation between the fractal dimension...

...Guangyao Li; Ted Belytschko The total Lagrangian formulation and implementation of the element‐free Galerkin method (EFG) is presented for the analysis of contact‐impact problems with large deformations and for the simulation of metal forming processes. An integration scheme based on stress points...

...Eric Perkins; John R. Williams Presents a new contact detection algorithm based on double‐ended spatial sorting (DESS) that is insensitive to variations in object size. It was developed to address the problems that arise when objects with non‐spherical geometry and non‐uniform sizes are simulated...

...A. Rieger; P. Wriggers Several a posteriori error indicators and error estimators for frictionless contact problems are compared. In detail, residual based error estimators, error indicators relying on superconvergence properties and error estimators based on duality principles are investigated...

...Claude Blanzé; Laurent Champaney; Pierre Vedrine This paper focuses on the design of a superconducting quadrupole prototype. This structure includes many frictional contact zones, and the loading conditions are complex (mechanical, thermal and magnetic). A dedicated computational strategy, based...

... and regularization processes, for which reason we developed a procedure for its updating. This procedure is of more importance in the case of contact problems, its primary object being to avoid interpenetration. The work was done in the ZATILAN code, developed by the Department of Mechanical Engineering...

...G. Zavarise; P. Wriggers The numerical solution of contact problems via the penalty method yields approximate satisfaction of contact constraints. The solution can be improved using augmentation schemes. However their efficiency is strongly dependent on the value of the penalty parameter...

...C. Blanze; L. Champaney; J.‐Y. Cognard; P. Ladevèze Presents a modular method for obtaining either a quick or a precise calculation for three‐dimensional structure assemblies with local non‐linearities, such as unilateral contact with friction, or technological components, such as prestressed bolt...
