How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Defects in composite structures, such as voids, cannot entirely be avoided during the manufacturing, and have detrimental effect on the damage behavior and mechanical properties. The main characteristics of voids in composites are void content, shape, size, location and distribution. To investigate the effect of void characteristics on the failure...
The characterization and evaluation of uncertainties caused by the automated manufacturing procedure are essential for the early structural design and application of 3D woven composites. To account for the inherent uncertainties, numerical simulations must be integrated with statistical uncertainty quantification and propagation methods. However, i...
A novel in situ experimental-numerical approach combining the meso-scale Digital Image Correlation (DIC) and a cohesive zone model (CZM) is proposed to assess the in situ interfacial strength of 3D woven composites. In order to obtain a specimen with interface damage as the dominant damage mode and simple internal structure, the specimen is particu...
This paper investigates the compressive damage mechanisms of 3D woven composites through a coupled numerical-experimental approach. A comprehensive progressive damage model, capable of characterizing the fiber kinking failure, transverse inter-fiber crack, matrix damage and interfacial debonding, is developed to capture the damage accumulations by...
