SUMMARY
The stiffness matrix for a plate element in finite element analysis (FEA) is derived from the formula for line elements, specifically using the equation fl/ae, where 'a' represents the area, 'l' is the length, 'f' is the applied force, and 'e' is Young's modulus. To compute the local stiffness matrix for a 3D plate element, an algorithm is required to index the degrees of freedom (DOFs) of each node. It is recommended to search for open-source code in finite element resources or to develop a custom solution if the user is already engaged in the coding process.
