Abstract (EN): Unbounded continua arise in many engineering problems, particularly those involving geo-mechanical situations. The traditional engineering approach of simple truncation introduces problems of positioning the finite boundary for accurate solution. In this paper mapped infinite elements are coupled to conventional elements in order to model the far field response and attention is focussed on problems in which plastic flow takes place. Various families of mapped infinite elements are considered and details of their formulation and computer implementation are provided. The applicability of this finite/infinite element approach is assessed by the solution of both two and three dimensional elasto-plastic examples. © 1984.
