Dislocation density reduction in multicrystalline silicon through cyclic annealing
… were modeled using finite element analysis (FEA) on Abaqus CAE and compared to the dislocation density reductions observed in the lab. As too low of stress will have no effect on dislocation density reduction and too high of stress will cause dislocations to multiply, it is important to find …

Characterization of anodic bonding
… curvature, and microstructured interfacial features for CVD SiC anodic bonding were shown to be comparable to single crystal silicon (Si) anodic bonding. The Plaza Test specimen, invented by Plaza et al., was used to assess bulk and thin-film, lapped glass bond quality. A two-part …

Multilayer Ionic Transducers
… during bending. A Finite Element Analysis (FEA) method capable of modeling the structure of the multilayer transducers is developped. It is used to model the interfacial friction in multilayer transducers. Experiments on transducers with one to three layers are performed and the results are …

Elastomeric bearings in high demand applications : numerical study and experimental validation
Pot and disk bearings are typically used in high-demand bridge applications where significant demands are imposed on bearings at the supports to accommodate rotations and complex bridge movements from both environmental thermal loads and vehicular traffic. However, past bridge research, design, and …

Investigation of Weldability in High-Cr Ni-base Filler Metals
… that provides a cooling rate of 160 C/s based on FEA modeling, compared with the previous cooling rate of 245 C/s, while maintaining feasibility of the CPTT. A longer pin length is required to cause cracking with the redesigned molds when compared with the previous molds. Also, significant crack …

Fully Distributed Multi-Material Magnetic Sensing Structures for Multiparameter DAS Applications
… single mode fiber up to 1-km. Due to extensive FEA modeling, multiple iterations of the magnetic sensor were fully characterized and an equation describing the relationship between sensor design and strain transfer has been created and validated experimentally. Multi-parameter tests including …

Structure-thermal coupling in viscoelastic material in rubber bushing of vehicle system
… excitation. Furthermore, with appropriate modeling, two heat generation mechanisms of rubber bushing are explored and their thermal fields are investigated. Due to the nonlinear force-deflection relationship of the viscoelastic material, finding satisfactory mechanical properties of rubber …

Advanced automated detection of foreign object debris (FOD) in woven and uni-directional composite laminates.
… preliminary studies with mechanical testing and FEA have been done. The work is further expanded by inserting FODs of different materials, sizes, shapes, depths in both the unidirectional and woven CFRP and comparing the results. In total over 900 individual FODs are studied covering the above …
