An integrated viscoelastic modeling framework combining analytical and FEM approaches: Application to WSe2 coatings
Mohamed Bensalem, Fateh Bahadur, Yue Wang +2
This work presents an integrated methodology combining analytical and finite element FEM based viscoelastic modeling for characterizing the nanoindentation response of coatings. Th…
Physics-Constrained Inverse Estimation of Irradiation-Induced Strain in He-H Ion-Implanted 4H-SiC Using Nanoindentation and Finite Element Modeling
M. Bensalem, N. Daghbouj, J. Duchon +8
Nanoindentation is widely used to evaluate the mechanical properties of irradiated materials however its potential for quantifying irradiation induced subsurface strain remains und…
Defect Landscape Engineering Suppresses Helium Damage in Ceramics
Nabil Daghbouj, Ahmed Tamer AlMotasem, Bingsheng Li +12
Helium accumulation in structural ceramics used in nuclear, fusion, and aerospace systems causes swelling, cracking, and early failure, yet controlling this damage has remained elu…
Asymmetrical Defect Sink Behaviour of HCP/BCC Zr/Nb Multilayer Interfaces: Bubble-Denuded Zones at Nb Layers
Nabil. Daghbouj, H. S. Sen, Mohamed BenSalem +11
Radiation induced helium bubble formation poses a major challenge to the structural integrity of materials in nuclear energy systems. In this study, we investigate defect evolution…
