Euler-Bernoulli and Timoshenko beam simulations#

Contains examples for static and dynamic simulations.

Both Euler-Bernoulli (default, cubic Hermitian) and Timoshenko (pure Lagrange + selective reduced integration) elements are supported. Toggle via Simulations.Beam(mesh, structure, useTimoshenko=True) — see Beam2 for a worked example.

Digital Image Correlation (DIC) analyses#

Contains examples for dic analyses.

DIC1

Hyperelastic simulations#

Contains examples for static and dynamic simulations in the Lagrangian framework.

Also includes sympy scripts to construct new hyperelastic laws.

ComputeHyperelasticLaws

Linearized elastic simulations#

Contains examples for static, dynamic, contact, homogenization and mesh optimization.

“MachineLearning” tests#

k_means

Meshes#

Scripts demonstrating how to construct Mesh.

PhaseField damage simulations for quasi-static brittle fracture#

Scripts that demonstrate phase-field damage simulations.

To enable fast execution, these examples use coarse meshes and large loading steps. In practice, fine meshes and smaller increments are essential to obtain realistic and accurate results.

For more realistic simulations, make sure you use a finer mesh and smaller loading steps by setting meshTest=False.
