Predicción de fallas por grietas longitudinales en soldaduras de acero aisi 1045 con el proceso smaw mediante análisis por elementos finitos

Abstract

This project focused on addressing the issue of failures in AISI 1045 steel welds using the SMAW welding process, employing modeling techniques and finite element analysis. The need to prevent and understand these failures was critical for improving the reliability of structures incorporating this type of welding. The project was based on an exhaustive review of scientific literature and the generation of specific three-dimensional models for V-joints in AISI 1045 steel, considering realistic working conditions. These models allowed for the simulation of loads and temperatures to which the welds would be subjected, and fatigue analyses were conducted to evaluate the lifespan of these joints in this specific context. It was anticipated that the results of this research would contribute significantly to a deeper understanding of longitudinal crack failures in AISI 1045 steel welds performed using the SMAW process. This, in turn, would lead to improvements in the quality and safety of structures employing these welded joints. Furthermore, the methodology developed could be applied and transferred to similar analyses in other materials and situations, benefiting both industry and the academic research community in the field of materials and structural engineering.
