 Finite element method in structural mechanics

The Finite Element Method (FEM) is a numerical technique used to find approximate solutions to boundary value problems for partial differential equations, particularly in the field of structural mechanics. It is widely used for analyzing complex structures under various loads and boundary conditions. Here’s a breakdown of the method: ### Key Concepts of Finite Element Method: 1. **Discretization**: - The first step in FEM is to divide the complex structure into smaller, simpler parts called finite elements.
