RESUMO

The Boundary Elements Method was employed in the study of the transient effect of the temperature in heat conduction problems for plain elements. The purpose was to present a formulation using linear continuous or discontinuous boundary elements with nodal parameters fixed at the ends of elements. The collocations points were positioned at the ends of continuous elements or shifted to the interior of elements in case of discontinuous elements. The integrations were performed with analytical expressions for the case of collocation points belonging to the boundary element and the Gauss-Legendre quadrature for other cases. A computer code was developed with the C/C++ programming language which had a simplified explanation included in the text. The results were compared to available solutions in the literature to show the precision of the formulation
