Finite element analysis

Definition

Finite element analysis (FEA) is a computational method used to predict how objects behave under various physical conditions by breaking them down into smaller, simpler parts called elements. This technique allows for the simulation of complex structures and materials, making it invaluable in understanding stress, strain, and deformation in biological tissues, protective gear, and customized equipment.
