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…
Cross-sectional helium irradiation reveals interface-controlled bubble evolution in Cr/CrAlSiN multilayer coatings on zirconium alloys
Renda Wang, Xue Bai, Xueliang Pei +9
The irradiation stability of Cr based protective coatings on zirconium alloys is critical for the development of accident-tolerant fuel claddings. However, conventional surface irr…
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…
A comparative nanotribological investigation on amorphous and polycrystalline forms of MoS2
Hesam Khaksar, Prashant Mittal, Nabil Daghbouj +3
The wear behavior of two amorphous and polycrystalline forms of MoS2 prepared by magnetron sputtering has been characterized in a combined nanoindentation and atomic force microsco…
