High-velocity impact failure modeling of Armox 500T steel: Model validation and application to structural design
Download2023-01-01
Mao, Kyle, Toussaint, Geneviève, Komrakova, Alexandra, Hogan, James D.
As an advanced fracture model, the Generalized Incremental Stress State dependent damage MOdel (GISSMO) provides non-linear damage accumulation formulation to better predict ductile fracture initiation associated with a wider range of material stress states. In this study, we simulate the...

Pisavadia, Harshil, Asad, Asad, Sameoto, Dan, Dolez, Patricia, Hogan, James D.
This work utilizes predictive modeling techniques to guide and inform metamaterial design for heat management solutions and thermal radiation control. Specifically, micro- and macro-scale polyethylene-based solutions are proposed for passive and active thermal camouflage. A micro-scale post...
