Analysis of the Bar Problem Under Normal Force via Unconventional Formulations of the Finite Element Method José Vieira de Melo Neto, Luis Armando Piccino Navarro, Edson da Costa Eduardo, Stefan Hass, Rafaela Rodrigues Gomes, Wesley Góis

This work highlights the application of unconventional formulations of the Finite Element Method (FEM) to the analysis of the classical one-dimensional Structural Mechanics problem of a bar subjected to axial loading. Specifically, the Hybrid-Mixed Stress Formulation (HMSF), the Generalized Finite Element Method (GFEM), the Stable Generalized Finite Element Method (SGFEM), and the application of GFEM and SGFEM within the HMSF framework are employed in the numerical simulation of this problem using MatLab® and SMath®.
