The Al2O3 ALD films on SiO2, Si and PI substrates exhibited quite different scratch morphologies and failure modes.
Morphology features and failure mechanisms of thermal barrier coating (TBC) systems under thermal cycling are very complicated as it is influenced by many factors.
The morphology, deformation and failure behaviour of new high-performance polyimide (PI) fibres were examined by scanning electron microscopy (SEM), wide angle X-ray diffraction (WAXD) and tensile measurements.
Although multiple mechanisms of device attachment to the spinous processes exist, there is a paucity of data regarding lumbar spinous process morphology and peak failure loads.
Final deformation photographs and scanning electron micrographs of the bamboo microstructures clearly illustrated their damage morphologies and various failure mechanisms, including fiber buckling, fiber fractures, PCs collapse, delamination and crack propagation at different strain rates and loading directions.
The crashworthiness testing of carbon/epoxy composite tubes is conducted in this study, and the corresponding energy-absorbing parameters and failure morphology are discussed.
This relative coverage of the braided yarn to polymer film played an important role in determining the mechanical performance of the stents, including the compression and recovery behavior as well as the tensile properties and failure morphology.
The meso-scale model effectively predicted mechanical properties and failure morphologies of the 3D braided composites with detailed information on distributions of deformation and stress in braiding yarns.
It can influence the fracture morphology both in propagation path and failure pressure greatly.
In this study, the model is used to simulate the damage propagation, failure morphology and energy absorption in triaxially braided composite tubes under axial compression.
