The Finite Element Method (FEM) has emerged as the cornerstone of modern structural analysis in industrial engineering. This paper presents a comprehensive review of structural analysis techniques employing FEM, with particular emphasis on industrial applications including aerospace, automotive, civil infrastructure, and manufacturing sectors. The review systematically examines the evolution of FEM formulations -- from classical linear static analysis to advanced nonlinear, dynamic, and coupled multi-physics simulations. Key aspects including mesh generation strategies, element types, solver technologies, convergence criteria, and validation methodologies are critically analyzed. Furthermore, the integration of FEM with modern computational paradigms such as topology optimization, isogeometric analysis, extended finite element method (XFEM), and machine learning-assisted simulation is discussed. The paper also surveys widely adopted commercial and open-source FEM software platforms, along with their respective industrial use cases. Challenges such as computational cost, model uncertainty, and limitations in simulating complex boundary conditions are highlighted. The review concludes with emerging trends and future directions of FEM in industrial structural analysis, including real-time simulation, digital twin frameworks, and high-performance computing. This work serves as a consolidated reference for researchers and engineers seeking a holistic understanding of FEM-based structural analysis in industrial contexts.
