lujuusmatriisi
Lujuusmatriisi, or stiffness matrix in English, is a fundamental concept in structural analysis and mechanical engineering. It is a mathematical representation of how a structure or a mechanical component deforms under applied loads. Specifically, the stiffness matrix relates the forces and moments acting on a system to the displacements and rotations it experiences.
In the context of finite element analysis (FEA), the stiffness matrix is a core component. A structure
The entries of the stiffness matrix are derived from the material properties (like Young's modulus and Poisson's
