Influência do Tamanho da Malha em Simulações Numéricas Via Elementos Finitos.

New structural systems in civil construction are always emerging, and therefore a performance evaluation is necessary. For this evaluation, laboratory tests are necessary, but, due to the scarcity of research centers, numerical simulations have emerged as an alternative. For better reliability in the results obtained in the simulation, a mesh test is necessary, verifying the influence of the results. In this paper, the analysis of are two main types of mesh (tetrahedral and hexahedral) and several possible discretization sizes, aiming to evaluate the parameters in a numerical simulation of a specimen requested with 3-point static bending. Two mesh types and three sizes (1mm, 5mm and 10mm) were adopted. Through the obtained results, it can be reached that the tetrahedral mesh obtained better results. It was also possible to achieve that the mesh size did not change the results of stresses and displacements in the contour of the part, only influencing the results of stresses in the interior.
