NUMERICAL MODELING OF CONVENTIONAL STEEL, STAINLESS STEEL AND INCONEL ALLOY SOLID ELEMENTS THROUGH THE FINITE ELEMENT METHOD

Resumo

The work will present the development and implementation of linear numerical models, with the
objective of performing mechanical analyzes on solid elements of conventional steel (MS250 and HS350),
stainless steel (SS304) and inconel alloy (IA718). For this, we intend to implement computationally, with the aid
of the FORTRAN programming language, a mathematical formulation based on the Finite Element Method
(FEM), whose purpose will be to obtain the values of deformations and nodal displacements at different points of
the parts, in addition to the von Mises stresses in each finite element that compose the structures. For the
discretization of solid elements, 4-node tetrahedral (T4) and 8-node hexahedral (H8) finite elements were used.
For a greater scope of validation of the implemented module and to prove its efficiency, solids with different
geometric and physical characteristics will be analyzed. In order to verify the responses obtained from the
implemented computational program, comparisons will be made with results found in the literature.
