- Geometry
- Standard linear solid at eps=0.01: E0=2000 MPa, Einf=1000 MPa, tau=5 s.
- Material
- Constitutive or analytical definition: E_R(t)=Einf+(E0-Einf) exp(-t/tau); sigma=E_R eps0.
- Boundary conditions
- Required solver capability: prony_series. Use the loading/path control stated in the setup and preserve the complete response history.
- Measured quantity
- sigma(0)=20 MPa, sigma(5 s)=13.6787944117 MPa, sigma(10 s)=11.3533528324 MPa, sigma(infinity)=10 MPa.
