Abstract
This research investigates the application of Isogeometric Analysis (IGA) in solid mechanics, particularly in plane stress analysis. It aims to evaluate the effectiveness of IGA compared to the Finite Element Method (FEM) and analytical solutions. IGA combines precise geometry modeling with accurate numerical analysis, enabling the modeling of complex surfaces and integration with CAD and CAE systems. It offers improved accuracy and efficiency in structural applications where traditional FEM may have limitations. The study explores different enrichment techniques, including h-refinement, p-refinement, and k-refinement, to enhance numerical solutions, accuracy, and efficiency. By implementing IGA with NURBS basis functions and conducting numerical simulations, the research analyzes structural behavior under plane stress conditions. The results highlight the superior accuracy achieved by k-refinement compared to hp-refinement, emphasizing the significance of control point distribution. Moreover, IGA demonstrates its capability to accurately reproduce stress distributions in problems with complex geometries, such as plate with central hole, similar to analytical solutions. Overall, this research advances the understanding and application of Isogeometric Analysis in solid mechanics, showcasing its potential as a robust tool for precise and efficient numerical modeling in engineering practice.
