1.	Different Beam-Column Finite Element Formulations for Geometric Nonlinear Analysis with Large Displacements Luís Eduardo Silveira Dias and Amilton Rodrigues da Silva International Journal of Advances in Engineering & Technology (IJAET), Volume 18 Issue 6, pp. 202-224, December 2025. ABSTRACT The structural elements that make up the most varied structures used in structural engineering are increasingly slender. The mechanical behavior of these slender elements generally presents strongly nonlinear equilibrium paths in terms of their configuration changes, which leads to the need for specific strategies to solve the problem. In this sense, this work presents different 2D beam-column finite element formulations based on the total and updated Lagrangian and co-rotational references. As a contribution of this work, one of the co-rotational formulations considers that the length of the element is dependent on the nodal displacements, that is, a general form of the co-rotational formulations found in the literature. The objective is to verify the influence of this consideration in the analysis of plane frames with large displacements. The presented formulations are validated through the responses obtained from the analysis of different classic examples in the literature. In these analyses, it was observed that the element based on the total Lagrangian cannot represent the geometric nonlinear behavior from a displacement limit, and that the formulation considering the variation of the element length with the nodal displacements generated a small difference compared to the constant element length, justifying this simplification adopted in all formulations found in the literature. However, one of the examples analyzed shows that for high values of the inertia/area ratio, this simplification can lead to poor responses.	202-224	Online
2.	Development of a Computational Tool for the Structural Design of Footings Gustavo Batista Pimentel, Pedro Paulo Martins de Carvalho, Kuelson Rândello Dantas Maciel, José Leonardo Vanderlei de Carvalho, Pedro Cláudio dos Santos Vieira and Cláudio Alex de Oliveira Pires International Journal of Advances in Engineering & Technology (IJAET), Volume 18 Issue 6, pp. 225-237, December 2025. ABSTRACT The efficient and safe design of foundation elements is critical in structural engineering, requiring specialized computational support. To support this, several computational tools have been developed to facilitate project execution and organization. In structural design, for instance, it is often necessary to determine the dimensions of foundation elements. In this context, the present work proposes the development of a computational tool for the design of isolated footings, with a dual purpose: to serve as a didactic resource in undergraduate education and to assist designers who wish to carry out manual calculations. Developed entirely in Python, the tool’s primary value lies in generating reliable results directly comparable to those found in established reference literature, thus facilitating validation. The program generates a comprehensive calculation report, which transparently presents a step-by-step application of the design equations, including all partial intermediate results at each stage, thereby improving the user's understanding of the underlying design methodology. An accompanying user manual was developed and presented for the tool. The program's substantial pedagogical value is demonstrated by its intuitive visual representation of the footing geometry, which consequently streamlines the definition and input of critical design parameters, such as column dimensions, axial load, bending moments, material resistance properties, and concrete cover.	225-237	Online
3.	Effect of Milling Parameters on Chip Characteristics of a (Mg-Zn-RE) Magnesium Alloy Alison Alex Veloso Alves, Marcos Guilherme Carvalho Bráulio Barbosa, João Rodrigues de Barros Neto, Raphael Lima de Paiva International Journal of Advances in Engineering & Technology (IJAET), Volume 18 Issue 6, pp. 238-256, December 2025. ABSTRACT The Magnesium (Mg) alloys containing rare earths (RE), have gained prominence due to their low density and high specific strength. However, the effects of machining parameters on chip formation are not fully understood. In this context, this study aims to investigate the influence of milling conditions (milling mode, edge radius, feed rate, and depth of cut) of the (Mg-Zn-RE) Mg alloy on the characteristics of the chips, with regard to morphology, thickness, microstructure, and hardness. Sixteen cutting conditions were evaluated, combining two milling modes, two edge radius (r?) levels, two feed rate (f) levels, and two depth of cut (ap) levels. The analysis involved the use of characterization techniques such as optical microscopy (OM) and Vickers microhardness (HV). Results indicate that conditions with ap = 2 mm generate arc-shaped chips, and ap = 1 mm tend to be comma-shaped, while discordant conditions significantly influence chip fragmentation. Higher f (0.8 mm/rev) and up-milling increase chip thickness. Microstructural analysis shows increased precipitate density and plastic deformation, reflecting work hardening. Although microhardness was not significantly altered by the cutting parameters, conditions under discordant cutting and a smaller f (0.01 mm) produced harder chips, and in comparison, with the material “as received,” there was a significant increase in the microhardness of the chips.	238-256	Online
