Abstract
In this paper, a novel unique coordinate ascent mapping
formulation for infinite elements. is developed. Reciprocal,
exponential, and logarithmic are the decay types with which
the proposed formulation is concerned. As a matter of
generalisation, each decay type may be utilised through any
optional decay pattern. An inherent characteristic in this
postulated formulation is its capability of providing an
arbitrary pole position, which is not given a due
consideration in any of the earlier formulations. The
mapping and shape functions for several two- and three-dimensional
elements as well as a flow diagram for finite/infinite-element stiffness subroutine are presented.
The proposed formulation is tested for a number of one-,
two-, and three-dimensional infinite-domain problems.
