✦ Synopsis

This paper presents a perturbation and ®nite±boundary element combined approach for solving the problem of linear creep. Compared with the conventional incremental method, the ®eld variables, without assumptions of remaining constant or varying linearly with time within a discretised time interval, can be described more precisely. The recursive formulae of perturbation for boundary±®nite elements are constructed with the consideration of reinforcement. Numerical veri®cation of the approach proposed gives good correlation against analytic solutions. This encourages the extension of the work.

The p-version of the finite element method is applied to solve the singularly perturbed two-point boundary value problem with or without turning point. With the special choice of mesh points, global error estimates are derived. In some cases, the exponential rate of convergence is obtained. Some num
