Problem statement

Geometry: Use the open Abaqus viscoelastic-damper model with Prony/Maxwell calibration and coupled temperature-displacement analysis.
Material: Constitutive or analytical definition: Cross-solver history plus exact first-law energy accounting.
Boundary conditions: Required solver capability: thermorheology_and_dissipative_heating. Use the loading/path control stated in the setup and preserve the complete response history.
Measured quantity: No independent scalar target found; compare force-displacement hysteresis and temperature histories to the official model and require mechanical dissipation to equal generated heat plus stored-energy change.
