Journal ArticleDOI
Open hole and filled hole progressive damage and failure analysis of composite laminates with a countersunk hole
TL;DR: The Intra-inter crack band model (I2CBM) as discussed by the authors is a unified approach for modeling intralaminar and interlaminar progressive damage and failure in polymer matrix composites.
Journal ArticleDOI
Effect of automated fiber placement (AFP) manufacturing signature on mechanical performance of composite structures
Minh Nguyen,Avinkrishnan A. Vijayachandran,Paul Davidson,Damon Call,Dongyeon Lee,Anthony M. Waas +5 more
TL;DR: In this article, a comprehensive and detailed experimental study of the influence of imperfections caused during Automated Fiber Placement (AFP) manufacturing is reported, which shows significant knockdown in stiffness and strength due to gaps, with larger gap sizes showing higher knockdown.
Journal ArticleDOI
Mechanics of kinking in fiber-reinforced composites under compressive loading:
Paul Davidson,Anthony M. Waas +1 more
TL;DR: In this paper, a novel approach to analyze kink banding failure in fiber reinforced composites is presented by considering a single fiber-matrix unit cell and utilizing a fiber deformation represen...
Journal ArticleDOI
Experimental determination of validated, critical interfacial modes I and II energy release rates in a composite sandwich panel☆
TL;DR: In this paper, a validated experimental approach to obtain critical mode I and mode II energy release rates for interfacial failure in a sandwich composite panel is outlined by modifying the geometry of the sandwich structure to align the face sheet-core interface to coincide with the neutral axis.
Journal ArticleDOI
The effects of defects on the compressive response of thick carbon composites: An experimental and computational study
Paul Davidson,Anthony M. Waas +1 more
TL;DR: In this article, the effects of defects on lowering the compressive strength of unidirectional carbon fiber polymer matrix composites are reported, and a finite element based mechanics model is implemented, allowing for kinking and splitting of composite layers.
