Finite Element Analysis

Definition

Finite Element Analysis (FEA) is a computational technique used to predict how structures behave under various physical conditions by breaking them down into smaller, simpler parts called finite elements. This method allows for detailed simulations of complex materials and geometries, making it essential for evaluating the performance of biomimetic materials in real-world applications.
