Multi-Scale Experimental Characterization for LS-DYNA MAT213 Modeling of Composite Structures under High Strain Rate
Jackob Black, Ryan Premo, Robert K. Goldberg +3
Aerospace structures often experience high strain rate events such as ballistic impact, crash, or crush. A material model has been developed that enhances the capability to simulat…
Experimental Investigation of the Structural Performance of Composite Structures Produced using Additive Manufacturing
Hunter Watts, Ryan Premo, Wayne Huberty +2
This project is focused on investigating the structural performance of parts and structures produced using the latest additive manufacturing techniques. For additive manufacturing…
Experimental Characterization of Non-Associative Plasticity Flow Rule Coefficients for the LS-DYNA MAT213 Model
Ryan Premo, Jackob Black, Michael Pereira +3
This project is focused on developing an experimental framework for characterizing non-associative plasticity flow rule coefficients through coupon-scale tests for the LS-DYNA MAT2…
Experimental multi-scale characterization of mode-II interlaminar fracture in geometrically scaled stitched and unstitched resin-infused composites
Dawson Ozborn, Jackob Black, Wayne Huberty +2
This work is focused on investigating the impact of out-of-plane stitches on enhancing mode-II interlaminar fracture toughness (or energy) and characterizing damage progression and…
Experimental characterization of cohesive laws for mode-II interlaminar fracture in geometrically scaled composites using through-thickness deformation analysis
Han-Gyu Kim, Ryan Howe, Richard Wiebe +3
This work proposes an experimental framework to characterize a cohesive law for mode-II interlaminar fracture and demonstrates its implementation. For a size effect study, geometri…
