What Are The Challenges Of Large Deformations In FEM? Ever wondered what challenges engineers face when analyzing structures that undergo large deformations? In this detailed video, we explore the complexities involved in finite element method (FEM) analysis when structures experience significant shape changes. We cover key issues such as geometric nonlinearity, material nonlinearity, and the difficulties in updating the mesh as the structure deforms. You'll learn how advanced computational methods, like incremental and iterative solutions, are used to handle these challenges effectively. We also discuss the importance of contact detection, boundary condition management, and the increased computational resources required for accurate results. Additionally, the video explains the mathematical frameworks, such as the updated and total Lagrangian methods, which help describe large deformation behaviors. These concepts are essential in real-world applications like metal forming, rubber components, biomechanics, and crash simulations, where predicting behavior under extreme conditions is critical for safety and performance. Whether you're a student, researcher, or professional in mechanical engineering, understanding these challenges will help you design better models and select appropriate analysis techniques for large deformation problems.
