  Materials: Multiphysics Simulations of a MEMS-Based Creep Device Under Io
 n Irradiation\n\nAbstract:\n\nQualification of structural materials for ad
 vanced nuclear reactors requires testbeds capable of\nsimultaneously repli
 cating and monitoring high temperatures\, irradiation\, and mechanical str
 ess.\nThis talk presents a multiphysics modeling framework for the design 
 and optimization of an in-\nsitu testbed for measuring irradiation creep a
 nd thermal fatigue.\nThe testbed couples a silicon MEMS device with ion ir
 radiation and scanning electron\nmicroscopy to enable real-time mechanical
  testing under irradiation. Finite element simulations\ndeveloped in CUBIT
  and BISON resolve the coupled thermal\, electrical\, and mechanical\nresp
 onse of the MEMS device and quantify induced strain in the sample. Geometr
 y optimization\nof the MEMS device is performed to achieve uniform tempera
 ture and strain fields in the test\nsample.\nResults demonstrate that the 
 multiphysics framework reduces reliance on iterative physical\nprototyping
  in testbed development and provides a reproducible basis for geometry and
  loading\nparameter selection in nuclear materials testing.\n\nSpeaker: Ak
