The&nbsp;experimentally obtained temperature field is used as input for the numerical BEM analysis in&nbsp;order to represent the thermal expansion effect. The domain’s temperature and consequent&nbsp;resultant thermoelastic displacement fields are carried into the BEM formulation using the Radial Integration Method (RIM). This method consists in a mathematical technique where&nbsp;the radial basis functions are applied to convert domain integrals to the boundary. The use of&nbsp;the RIM avoids the necessity of domain discretization and, therefore, preserves the BEM&nbsp;advantages. For this method to be effective, the experimentally obtained field that describes&nbsp;the temperature difference between the initial and final temperatures on the domain is described by a forth order polynomial. In the end, the resultant numerical displacement field,&nbsp;obtained from the experimental temperature field and the BEM analysis, is compared to the&nbsp;experimental displacement data in order to evaluate the numerical method efficacy. The&nbsp;verified proximity between the obtained numerical displacement curves and its experimental&nbsp;equivalents indicates the good performance of the proposed methodology.&nbsp;</p>}, number={6}, journal={Revista Interdisciplinar de Pesquisa em Engenharia}, author={Oberg, Matheus B.
