Solve linear static, transient, modal analysis, and frequency response
problems

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.

The toolbox lets you perform linear static analysis, transient analysis, modal analysis, and frequency response analysis. A typical programmatic workflow for solving a structural problem includes these steps:

Create a special structural analysis container for a solid (3-D), plane stress, or plane strain model.

Define 2-D or 3-D geometry and mesh it.

Assign structural properties of the material, such as Young's modulus, Poisson's ratio, and mass density.

Specify a damping model and its values for a dynamic problem.

Specify gravitational acceleration as a body load.

Specify boundary loads and constraints.

Specify initial displacement and velocity for a dynamic problem.

Solve the problem and plot results, such as displacement, velocity, acceleration, stress, strain, von Mises stress, principal stress and strain.

Approximate dynamic characteristics of a structural model by using reduced order modeling (ROM).
