Spall failure of alumina at high-strain rates using femtosecond laser experiments and high-fidelity molecular dynamics simulations
Mewael Isiet, Musanna Galib, Yunhuan Xiao +3
Ceramic materials are widely used in high-strain-rate applications due to their exceptional strength-to-weight ratio. However, under these extreme conditions, spall failure becomes…
Photo-induced spall failure of (111) twist grain boundaries in Ni bicrystals
Mewael Isiet, Mauricio Ponga
Spall failure, a complex failure mechanism driven by tensile stress wave interactions, has been extensively studied in single-crystal FCC metals, revealing a precursor stage involv…
AtomProNet: Data flow to and from machine learning interatomic potentials in materials science
Musanna Galib, Mewael Isiet, Mauricio Ponga
As the atomistic simulations of materials science move from traditional potentials to machine learning interatomic potential (MLIP), the field is entering the second phase focused…
Femtosecond two-pulse laser approach for spall failure in thin foils
Mewael Isiet, Yunhuan Xiao, Jerry I. Dadap +2
Spall failure in materials occurs when tensile waves, propagating through a material, interact leading to failure once the generated hydrostatic stress exceeds the material's stren…
Short-ranged ordering for improved mean-field simulation of disordered media: insights from refractory-metal high-entropy alloy carbonitrides
Okan K. Orhan, Mewael Isiet, Mauricio Ponga +1
Multi-principal element materials (MPEMs) have been attracting a rapidly growing interest due to their exceptional performance under extreme conditions, from cryogenic conditions t…
