This paper describes an efficient infinite element approach for the bo
undary element analysis of half-space problems. A decay function for s
tress analysis is then developed based on the theoretical displacement
attenuation away from the source of loading. Efficient order-adaptive
criteria are derived for numerical integration of the integrals over
the infinite boundary elements and illustrative results for rectangula
r foundation demonstrate the potential of the formulation. Copyright (
