Numerical methods in geomechanics / Численные методы в геомеханике

This volume contains the edited texts of the lectures and written discussions prepared for the NATO sponsored Advanced Study Institute (ASI) on "Numerical Methods in Geomechanics" promoted by the University of Minho, Braga, Portugal and held at Vimeiro Hotel (Torres Vedras) - August 24 to September 4, 1981. The object of the NATO-AS I has been to gather, as lecturers ,a wide range of scientists and engineers specialized on the above branch of knwoledgement in order to cover the whole variety of approaches for the solution of the set of problems concerning Geomechanics. In this way we could make available to the students, most of them researchers in this field, a large number of concepts, views and techniques for the solution of the problems they are concerned with. At the same time it was possible to disclose relationships between apparently different techniques for the solution of the same problem. For example some plasticity problems may be solved either by the usual finite elements technique or by mathematical programming or by the boundary elements method. Therefore, a link exi s ts amongs t thos e me thods. However, there has been in the pas t lack of effort to spring out these links, since there is a tendency for the researchers to stress the method they are working with and to forget about other methods, at least in what concerns their fundamentals. <...>
