Análise de vigas submetidas a solicitações térmicas pelo Método dos Elementos Finitos

Abstract

This work deals with the static analysis of the structural behavior of beams subjected to mechanical and thermal loads through the Finite Element Method (FEM). The analysis was performed numerically using this method and the Principle of Virtual Works, to develop a computational code, in the FORTRAN language, capable of simulating the behavior of these beams. The code includes input of the geometric, mechanical and physical properties of the beam, and generates the values of deflections and rotations of the structural element. Examples were presented for different situations, varying the properties, bindings and external loads, including thermal ones. The results obtained in the numerical model were then analyzed and compared with the analytical solutions and with the results obtained through a commercial program, verifying the effectiveness and precision of the developed code.
