Finite Element Analysis (FEA) is a computational technique used to predict how objects will respond to physical effects, such as stress, vibration, heat, and other forces. In FEA, a complex object is divided into smaller, simpler parts, known as “finite elements,” which are connected at points called nodes. By solving equations across these elements, FEA allows engineers to analyze the performance of a material or structure under various conditions, helping optimize designs and ensure safety and efficiency.
