One-Way Thermo-Mechanical Coupled System Identification Using Displacement and Temperature Measurements
Talhah Shamshad Ali Ansari, Suneth Warnakulasuriya, Ihar Antonau +3
Structural system identification in the presence of thermal loads is challenging, as unmeasured or poorly modeled thermal effects can mask or mimic damage, leading to unreliable co…

Adjoint-based Recovery of Thermal Fields from Displacement or Strain Measurements
Talhah Shamshad Ali Ansari, Rainald Löhner, Roland Wüchner +4
A finite-element method dependant adjoint-based procedure to determine the temperature field of structures based on measured displacements or strains and a set of standard loads is…

High-Fidelity Digital Twins: Detecting and Localizing Weaknesses in Structures
Rainald Löhner, Facundo N. Airaudo, Harbir Antil +3
An adjoint-based procedure to determine weaknesses, or, more generally, the material properties of structures is developed and tested. Given a series of load cases and correspondin…
