Book Synopsis Finite Element Approximation of Contact and Friction in Elasticity by : Franz Chouly
Download or read book Finite Element Approximation of Contact and Friction in Elasticity written by Franz Chouly and published by Springer Nature. This book was released on 2023-06-23 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the mathematics behind the formulation, approximation, and numerical analysis of contact and friction problems. It also provides a survey of recent developments in the numerical approximation of such problems as well as several remaining unsolved issues. Particular focus is placed on the Signorini problem and on frictionless unilateral contact in small strain. The final chapters cover more complex, applications-oriented problems, such as frictional contact, multi-body contact, and large strain. Finite Element Approximation of Contact and Friction in Elasticity will be a valuable resource for researchers in the area. It may also be of interest to those studying scientific computing and computational mechanics.

Book Synopsis Novel Nonlinear Finite Element Analysis of Dynamic Contact Problems Using Variational Inequalities by : Aleksander Czekanski
Download or read book Novel Nonlinear Finite Element Analysis of Dynamic Contact Problems Using Variational Inequalities written by Aleksander Czekanski and published by . This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic contact problems play an important role in dictating the integrity, performance and safety of many engineering systems/components involved in vehicle design, armament and ballistics, metal forming/cutting, and surface treatments, just to name a few. Despite their importance to the mechanical integrity of the systems examined, dynamic contact effects are frequently treated using oversimplifying assumptions, which neglect the main feature of the problem. This is because of the complexity of the governing system of equations. In this work, dynamic frictional contact problems are formulated using the more reliable and consistent variational inequalities (VI) approach. Three aspects of the problem are accordingly examined. The first is concerned with the development of the appropriate variational inequality formulations and solution strategies for dynamic frictional contact problems involving material and geometrical nonlinearity. Two models of surfaces are taken into account: (i) perfectly smooth surfaces, and (ii) more realistic surfaces, which take into account the change in compliance due to surface roughness. A new technique for representing the kinematic contact conditions is developed. Two newly devised numerical procedures are devised to solve the general dynamic frictional contact problem for elastic and elasto-plastic media. The first solution strategy, which regularises friction, is based upon the iterative use of mathematical programming and Lagrange multipliers. The second approach is accomplished using a nondifferentiable optimisation algorithm, through a sequence of mathematical programming sub-problems. The second aspect of the work is concerned with the selection of a suitable time integration scheme for contact problems. The values of the time integration parameters are so chosen to ensure that the solution is second order accurate, unconditionally stable, preserves energy and momentum during rigid impact, thus minimising numerical oscillations and ensuring optimal numerical dissipation. Finally, the developed algorithms are validated and applied to the analysis of several interesting engineering problems. The numerical predictions are compared to existing experiments as well as a commercial finite element code. The results reveal that the new dynamic friction contact formulations are more accurate than the traditional variational methods. These newly developed algorithms should provide designers with a powerful tool for treating dynamic elasto-plastic problems involving frictional contact.

Book Synopsis A Hybrid Elasticity and Finite Element Method for Three-dimensional Contact Problems with Friction by :
Download or read book A Hybrid Elasticity and Finite Element Method for Three-dimensional Contact Problems with Friction written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents a new hybrid elasticity and finite element method for general non-conforming contact problems. It is an iterative numerical procedure, which has distinct advantage over classical theory of contact since general geometrical and loading profiles with friction can be treated. And over the traditional contact solution approach in finite element method, it eliminates the use of gap elements and therefore the non-linearity in the solution enhancing accuracy and efficiency of the solution. For the two dimensional problems the equations were derived for a triangular pressure element. While for three-dimensional problems, the analytical solution was derived from Boussinesq and Cerruti equations for conical pressure elements, from which a semi-analytical approach to three-dimensional contact problems with friction was evolved to find the extent of the contact area and the loading distribution over this area together with the extent of the stick and slip zones. The linear static finite element method was then used to find the displacements and stresses throughout the two bodies in contact, which were analyzed separately with the knowledge of the area of contact and the traction over such an area. The method was used for non-conforming bodies but it can be extended to include different kinds of contact problems. The basic theory was presented for both two and three-dimensional non-conforming contact problem, together with algorithm, and numerical examples that showed the accuracy, efficiency and robustness of the method.

Book Synopsis Finite Element Analysis of Beam-to-Beam Contact by : Przemyslaw Litewka
Download or read book Finite Element Analysis of Beam-to-Beam Contact written by Przemyslaw Litewka and published by Springer Science & Business Media. This book was released on 2010-04-24 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phenomena occurring during a contact of two bodies are encountered in everyday life. In reality almost every type of motion is related to frictional contact between a moving body and a ground. Moreover, modeling of simple and more complex processes as nailing, cutting, vacuum pressing, movement of machines and their elements, rolling or, finally, a numerical simulation of car crash tests, requires taking contact into account. Therefore, its analysis has been a subject of many research efforts for a long time now. However, it is author’s opinion that there are relatively few efforts related to contact between structural elements, like beams, plates or shells. The purpose of this work is to fill this gap. It concerns the beam-to-beam contact as a specific case of the 3D solids contact. A numerical formulation of frictional contact for beams with two shapes of cross-section is derived. Further, a couple of effective methods for modeling of smooth curves representing beam axes are presented. A part of the book is also devoted to analyze some aspects of thermo-electro-mechanical coupling in contact of thermal and electric conductors. Analyses in every chapter are illustrated with numerical examples showing the performance of derived contact finite elements.
