Structural Mechanics
With structural analysis, you can predict how components behave under loading, vibration, and other physical effects. This helps you design robust mechanical components by validating designs through simulation and reducing the need for physical testing. For details about linear elasticity equations for plane stress, plane strain, and 3-D problems, see Linear Elasticity Equations.
You can perform linear static analysis, transient analysis, modal analysis, and frequency response analysis. The solver returns one of the results objects containing the basic solution values, such as displacement and velocity, at mesh nodes. After solving the problem, you can interpolate returned results to arbitrary spatial locations instead of mesh nodes and also evaluate other solution values, such as stresses, strains, and reaction forces.
