Rigid Offsets

This example tests the effect of rigid joint offsets in a diamond-shaped frame. The analytical solution is known, and the test is used to verify the correct treatment of offset geometry in a 3D frame element.

Concrete

Concrete

This example demonstrates how to construct and test the ASDConcrete3D material model under cyclic uniaxial compression. The simulation captures strain localization and damage evolution using an automatically regularized fracture energy.

Drucker–Prager Triaxial Test

Drucker–Prager Triaxial Test

This example simulates a conventional triaxial compression test using the Drucker–Prager model in a single 8-node brick element. Stress and strain response are recorded at the Gauss point.

010 - Nonlinear torsion

Test of the Wagner strain term with standard 6-DOF frame elements.

011 - Restrained torsion

Linear 7-DOF analysis of a cantilever subjected to a torque.

012 - Asymmetric Section: Linear warping

A transverse load induces twisting of a cantilever with an asymmetric channel section. Analysis is performed with both 6 and 7-DOF elements.

013 - Asymmetric Section: Post-buckling

Post-buckling curve with an asymmetric cross section

014 - Axial-torsional buckling

Simply supported channel, free to warp

017 - Torsional buckling under axial force.

A simply supported column buckles in torsion under the action of an axial load.
