Damage formation and evolution mechanisms in drilling CFRP with prefabricated delamination defects: Simulation and experimentation

open access: yesJournal of Materials Research and Technology, 2023
Delamination is a common defect in carbon fiber reinforced polymer (CFRP) during the molding process. Accurately understanding the formation and evolution mechanisms of drilling damage in CFRP with delamination defects is helpful for effectively ...

Anisotropic characteristics of layered backfill: Mechanical properties and energy dissipation

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
Layered backfill is commonly used in mining operations, and its mechanical behavior is strongly influenced by delamination parameters. In this study, 13 specimens with different numbers of delamination and delamination angle were prepared to investigate ...

Delamination thickness measurement based on Stoneley wave in bilayered composite structure

open access: yesActa Acustica, 2023
Introduction: For composite structures, delamination usually occurs at the interface. Ultrasonic guided waves have been widely used to detect the delamination.

Numerical Investigation on the Dynamic Evolution of Intra-Crustal Continental Delamination

open access: yesFrontiers in Earth Science, 2022
Delamination often occurs in continental regions, through which process the lithospheric mantle detaches from the continental crust and sinks into the underlying asthenospheric mantle. Various modes of continental delamination are proposed, including the

Delamination defects testing and evaluation of composite laminates using phased array ultrasonic technique

open access: yesCailiao gongcheng, 2021
Composite materials are prone to delamination defects during the preparation process. For the non-destructive testing and evaluation of carbon fiber reinforced polymer (CFRP) delamination defects, a standard specimen with embedded delamination defects ...

Difference in polypropylene fragmentation mechanism between marine and terrestrial regions

open access: yesSN Applied Sciences, 2021
Two kinds of marine polypropylene (M1-PP and M2-PP) and one land PP (L-PP) samples were collected from two beaches and land in Japan, respectively, to study the fragmentation mechanisms.

The role of intralaminar damages on the delamination evolution in laminated composite structures

open access: yesHeliyon, 2023
Delamination is a major failure mode affecting laminated composite structures. This failure mechanism, if not properly monitored, can lead to uncontrolled cracks growth and premature structural collapse.

Delamination and delamination magmatism

open access: yesTectonophysics, 1993
Abstract Lithospheric delamination is the foundering of dense lithosphere into less dense asthenosphere. The causes for this density inversion are thermal, compositional, and due to phase changes. For delamination to occur in the specific, and probably common, case where lithospheric mantle is intrinsically less dense than underlying asthenosphere ...

Delamination process in cross-ply UHMWPE laminates under ballistic penetration

open access: yesDefence Technology, 2021
Cross-ply unidirectional laminates made of ultra-high molecular weight polyethylene fibers are widely used as components of bullet-proof vests. To simulate the delamination process of the material under penetration, we constructed a numerical mechanical ...
