Key Concepts
- -- Finite Element Method (FEM)
- A numerical technique for finding approximate solutions to complex physical problems by dividing the domain into smaller, manageable elements.
- -- Principle of Potential Energy
- In equilibrium, a system will take a state that minimizes total potential energy; this principle underpins the derivation of stiffness equations in FEM.
- -- Element Stiffness Matrix
- A matrix that represents how an individual element of a structure resists deformation when forces are applied.
- -- Plane Stress
- A condition applied to thin plates, where stress is assumed to be negligible in the thickness direction.
- -- Plane Strain
- A scenario applicable to long bodies where strain in one direction is negligible and often taken to be zero.
- -- Domain Discretization
- The process of dividing a physical model into finite elements to facilitate analysis in the FEM.
- -- Verification and Validation (V&V)
- Verification ensures the computational model operates correctly, while validation ensures that the model accurately represents the real-world scenario it simulates.
- -- ComputerAided Engineering (CAE)
- Software tools used to support simulation and analysis, allowing engineers to conduct complex calculations and visualizations.
