摘要：

A novel parametric infinite element, in which the parametric axis extends to infinity, is presented. The proposed infinite element has the merit of simulating various simple decay patterns. First, the one-dimensional infinite element is explained. Then, generalization to derive higher-dimensional infinite elements is outlined. The proposed infinite element is integrated numerically using the conventional Gauss-Legendre abscissae and weights after being modified for unbounded ranges. The performance of the proposed infinite element is assessed by solving one-dimensional differential equations, the classical Boussinesq problem, and a case of a uniform pressure acting on an elastic medium of infinite lateral extent.
