Abstract
Discrete Damage Modeling is applied to complex sub-elements loaded in static and fatigue. Layered 8-node brick elements called LC3D8 elements were implemented for the first time in DDM models to reduce the computational requirements for modeling large and complex parts. Three sub-elements were tested and modeled: Fastener Pull Through (FPT), Hat Pull Off (HPO), and Three Point Bend with Flange (3PB-F). All three sub-elements were tested and simulated in quasi-static loading, while the 3PB-F was simulated in constant amplitude fatigue as well. Results demonstrate that DDM is capable of capturing peak load response accurately and damage initiation locations fairly accurately even with relatively coarse meshes.
