N2 - This paper presents the implementation of two creep rate equations in the boundary element method (BEM) to predict the creep strain rate at different temperatures and stresses. The creep analysis is basically applied to metals, but particular attention is focused on the numerical evaluation of creeping components subject to variable temperature. The constitutive model used in the numerical calculation is confined to standard power law creep equations. The direct formulation of the BEM is applied to secondary creep problems in a two-dimensional analysis. Numerical results are compared with solutions obtained from references to illustrate the accuracy of the proposed formulation, where a single test was simulated under the mentioned criteria.
