The effect of ply thickness on the free edge delamination of graphite/epoxy laminates
Thesis (M.S.)--Massachusetts Institute of Technology, Dept. of Aeronautics and Astronautics, 1985.

In-situ corrosion health monitoring and prediction in miltary vehicles.
… i.e. micro-cracks effects, blistering and edge delamination. These models can be used for the analysis of coating failure initiation and propagation, especially useful for coating life assessment. The models follow multidisciplinary approach coupling the concepts of thermodynamics, fracture …

Variable complexity modeling of postbuckled stiffeners for delamination initiation
Delamination at the free edge is analyzed as a mode of failure for uniaxial compression of postbuckled structural components. Analyses are performed for I-section stiffeners and for a dropped-ply laminate, all of which failed due to free edge delamination in earlier experimental studies. These …

Considerations of the Impedance Method, Wave Propagation, and Wireless Systems for Structural Health Monitoring
… are examined: transverse matrix cracking and edge delamination. With both composite defects, a sample is interrogated with the impedance method before and after damage is introduced. The exact amount of damage in each specimen is found using radiography and compared with the health monitoring …

Instability-related delamination growth of embedded and edge delaminations
… in composite laminates that have a near-surface delamination. This buckling causes load redistribution and secondary loads, which in turn cause interlaminer stresses and delamination growth. The goal of this research effort was to enhance the understanding of this instability-related delamination …

Understanding the Formation Mechanism of Plasma-sprayed Ni and Ni20Cr Splats through Experimental and Numerical Study
… microstructure, contact quality and edge delamination, were carefully characterised by FIB and TEM microscopes. Combined with the simulation results of energy conversion and fluid dynamics during droplet spreading, solidification was found to be crucial in generating splashing in the …

Scale effects in buckling, postbuckling and crippling of graphite-epoxy Z-section stiffeners
… The crippling mechanisms included flange free edge delamination at both nodal and anti-nodal axial positions, material crushing in the flange-to-web corner at nodal axial positions, and ply splitting in the flange-to-web corner at anti-nodal axial locations. The constraint of the potted end …
