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…
Partitioned Surrogates and Thompson Sampling for Multidisciplinary Bayesian Optimization
Susanna Baars, Jigar Parekh, Ihar Antonau +2
The long runtime associated with simulating multidisciplinary systems challenges the use of Bayesian optimization for multidisciplinary design optimization (MDO). This is particula…
A partitioned scheme for adjoint shape sensitivity analysis of fluid-structure interactions involving non-matching meshes
Reza Najian Asl, Ihar Antonau, Aditya Ghantasala +3
This work presents a partitioned solution procedure to compute shape gradients in fluid-structure interaction (FSI) using black-box adjoint solvers. Special attention is paid to pr…
