Abstract

Contact mechanics is a science that has a great impact on everyday life and is present in many different fields. These include civil, mechanical and environmental engin- eering, but also medicine since locomotion as well as functional joints do not work without friction. In one application friction is needed – like traction of car tyres – and in another application friction produces wear and costs – like in bearings. Thus it is of the utmost interest to have reliable and efficient methods and associated ana- lysis tools that can be applied to a vast range of contact problems. Using the power of today’s computers many complex contact problems can be solved with numerical simulation tools. Despite the progress that has been reached with respect to the implementation of contact algorithms in commercial codes, vivid research is still going on in the area of contact mechanics. Thus, within the last years, computational contact mechanics has been a topic of intense research. The aim of the development is to devise robust solution schemes and new discretization techniques, which can be applied to different problem classes in engineering and science. These are wide-ranging and include computational aspects of discretization tech- niques using finite and boundary element methods. Special solution algorithms for single- and multi-processor computing environments are of great interest for efficient solutions. Furthermore, multi-scale approaches have been applied suc- cessfully to contact problems and multi-field formulations were used for thermo- mechanical or electro-thermo-mechanical applications involving contact. Discrete element models include always contact and pose a challenge for the numerical treat- ment due to the high number of particles. Finally, problems like rolling wheels and tyres need special contact formulations and special algorithmic approaches. Technical applications incorporate different interface problems. Examples are failure processes in heterogeneous materials, textile and laminated composites, in- teraction between road and tyres, hip implants or artificial knee joints as well as spraying of particles on surfaces and impact analysis of cars. The present book summarizes work in the area of computational contact mechanics that was presented at the 1st International Conference on Computational Contact Mechanics in Lecce, Italy. The authors discuss different theoretical methodologies, algorithms for the solution of contact problems and apply these to different engineering problems.
