In these investigations elastic and non-elastic deformations, friction and adhesion phenomena are taken into account. All the necessary mathematical tools are given: local boundary value problem formulations, construction of variational equations and inequalities, and the transition to minimization problems, existence and uniqueness theorems, and variational transformations (Friedrichs and Young-Fenchel-Moreau) to dual and saddle-point search problems. Important new results concern contact problems with friction. The Coulomb friction law and some others are considered, in which relative sliding velocities appear. The corresponding quasi-variational inequality is constructed, as well as the appropriate iterative method for its solution. Outlines of the variational approach to non-stationary and dissipative systems and to the construction of the governing equations are also given. Examples of analytical and numerical solutions are presented. Numerical solutions were obtained with the finite element and boundary element methods, including new 3D problems solutions. 0aENGINEERING. 0aMATERIALS.14aENGINEERING.24aCONTINUUM MECHANICS AND MECHANICS OF MATERIALS.24aCOMPUTATIONAL INTELLIGENCE.1 aNeittaanmäki, Pekka J.eauthor.2 aSpringerLink (Online service)0 tSpringer eBooks08iPrinted edition:z9781402063763 0aSolid Mechanics and Its Applications,x0925-0042 ;v14740uhttp://dx.doi.org/10.1007/978-1-4020-6377-0zVer el texto completo en las instalaciones del CICY
