Preface

Since the second half of the last century there has been significant development in the methods used to solve applied problems of mechanics. There are a number of reasons for this. First, as a result of the increasing needs of technology the problems to be researched have become ever more complicated in themselves. Second, there is unprecedented quantitative growth, as well as improvement of the quality of computer equipment and the expansion of its capabilities. Finally, there is the development of computational methods associated with the achievements of mathematical physics and functional analysis. Techniques based on finite-dimensional approximation of differential and integral equations, such as the methods of finite differences, finite elements, as well as of influence matrices, have become widespread. Their advantage lies in universality and coverage of a wide class of problems. The di
