A combined X-Ray CT and mechanistic characterization of bearing failure mechanisms in bolted composite components
Cui, Xiaodong; Xiao, Jian; Lua, Jim Y.; Kariyawasam, Supun; Fulghum, Ethan; Saathoff, Caleb (Vertical Flight Society, 2021-05)This paper presents the characterization of bearing failure mechanisms in composite joints with countersunk bolt by applying an X-ray Computed Tomography (XCT) technique and a developed bearing failure model to build the ... -
Composite drilling characterization and performance evaluation
Xiao, Jian; Pham, Dinh Chi; Lua, Jim Y.; Saathoff, Caleb; Seneviratne, Waruna P. (DEStech Publications, 2019-09)Hole drilling is one of the most widely used operations in order to place bolts or rivets. Drilling holes in composites leads to drilling-induced defects and damages such as delamination, burr, microcracking, swelling, ... -
Experimental and numerical failure analyses of composite cruciform under biaxial static and cyclic loading
Pham, Dinh Chi; Xiao, Jian; Lua, Jim Y.; Perera, Shenal; Saathoff, Caleb (American Institute of Aeronautics and Astronautics Inc, AIAA, 2021-01)The characterization and prediction of multiaxial fatigue of composite structures have become a very important topic since aircraft composite structures and their repaired bonded structures are unavoidably subjected to ... -
High-fidelity response prediction and failure evaluation of tapered composite components under multiaxial loading
Xiao, Jian; Liu, Phillip; Pham, Dinh Chi; Cui, Xiaodong; Lua, Jim Y.; Perera, Shenal; Saathoff, Caleb (American Institute of Aeronautics and Astronautics Inc, AIAA, 2021-01)This paper presents an accurate and efficient modeling approach for high-fidelity 3D stress prediction and failure initiation and propagation modeling of tapered composite flexbeams with multiple ply drops subjected to ... -
A micro-macro coupling and physics informed modeling approach for bearing failure with x-ray CT characterization
Cui, Xiaodong; Xiao, Jian; Lua, Jim Y.; Kariyawasam, Supun; Fulghum, Ethan; Saathoff, Caleb (AIAA SCITECH, 2022-01-03)The failure mechanism of composite bolted joints was investigated using an in-situ X-ray CT technique with SSB test. A physics-informed modeling approach was proposed based on the traditional CDM method and a static bearing ... -
Multiaxial fatigue damage assessment of repaired composite cruciform specimens using stress ratio dependent fatigue damage accumulation model
Lua, Jim Y.; Xiao, Jian; Cui, Xiaodong; Kariyawasam, Supun; Fulghum, Ethan; Saathoff, Caleb (American Institute of Aeronautics and Astronautics, Inc., 2021-12-29)The paper presents a combined experimental and numerical study of multiaxial fatigue damage accumulation in scarf-repaired cruciform specimens subjected to fatigue loading. The existing fatigue analysis module is improved ...
