The present work focuses on the application and presentation of general aspects about the development of the specific computational module for the linear analysis of plane structures subjected to the action of external loads. This module is part of the solution package of the computer program developed and called NASEN. The numerical programming of the module is designed in a structured way and developed in a MATLAB environment. The physical theory of this module is based on the concepts of one-dimensional structural elements, thin plates and plane elasticity. The solution of the structural models is based on the approximate finite element procedures. Seeking to verify the applicability of the module, the numerical investigation is guided by four physical problems associated with the behavior of one-dimensional beams under elastic base, a thin plate rectangular, a free-clamped two-dimensional beam and a traction plate with a circular hole. The results obtained with the developed program module point to a similar behavior in relation to the reference solutions used in the test cases studied, indicating the precision and good performance of the code.
