- Geometry
- Uniform bar fully restrained axially: E=200000 MPa, alpha=12e-6 1/K, DeltaT=100 K.
- Material
- Constitutive or analytical definition: sigma=-E alpha DeltaT.
- Boundary conditions
- Required solver capability: thermal_strain. Use the loading/path control stated in the setup and preserve the complete response history.
- Measured quantity
- Axial stress=-240 MPa and total axial strain=0.
