“…This is because, according to these authors themselves, "no wave speed in the crystal depends only upon c 12 , it is no way to estimate it directly." It also is well-known that while c 12 and c 66 can be measured independently by static tests (Kunukkasseril et al 1975), these constants are always coupled in vibrations based measurements (Chaudhuri et al 2005;Chaudhuri and Balaraman 2007). Therefore, in Table 1 of supplementary material of the present investigation, both c 12 and c 66 , measured by ultrasound by Saint-Paul and Henry (1989), have been utilized (marked ***) in replacement of their counterparts due to Lei et al (1993) in order to assess the fracture characteristics of YBCO, and compare them with experiments by Cook et al (1987).…”

A novel eigenfunction expansion technique, based in part on separation of the thicknessvariable and partly on the Eshelby-Stroh type affine transformation, is developed to derive three-dimensional asymptotic stress field in the vicinity of the front of a semi-infinite through-thickness anticrack reinforcing an infinite orthorhombic single crystal plate, of finite thickness and subjected to far-field mode I/II loadings. Anticrack-face boundary conditions and those that are prescribed on the top and bottom (free or fixed) surfaces of the plate are exactly satisfied. The present investigation considers six through-anticrack systems reinforcing orthorhombic single crystal plates. Explicit expressions for the singular stresses in the vicinity of the front of a through-thickness anticrack reinforcing an orthorhombic plate, subjected to farfield mode I/II loadings, are presented. Finally, hitherto largely unavailable results, pertaining to the throughthickness variations of stress singularity coefficients corresponding to symmetric and skew-symmetric sinusoidal loads that also satisfy the boundary conditions on the top and bottom surfaces of an orthorhombic mono-crystalline plate under investigation, bridge a Electronic supplementary material The online version of this article (longstanding gap in the stress singularity/fracture mechanics literature.

“…Two types of hybrid multi-scale GFR/MWCNT/E composite laminates are fabricated using hand lay-up technique that developed for fabricating unidirectional and angle ply composite laminates by Khashaba [50] and applied in many publications [51][52][53][54][55][56]. The first type is the QI-GFR/MWCNT/E laminate and the second type is UD-GFR/MWCNT/E laminate.…”

This research aims to perform a symmetric investigation regarding the multiwall carbon nanotube (MWCNT) effect on the damping properties of different composite configurations. Nanophased epoxy is ultrasonically prepared and used to fabricate MWCNT/E nanocomposite as well as to hybridize advanced composite laminates with different fiber configuration. The hybridized composite laminates include, quasi-isotropic [0/45/90] s glass fiber reinforced nanophased-epoxy (QI-GFR/MWCNT/E) and unidirectional [0] 8 glass fiber reinforced nanophased-epoxy (UD-GFR/MWCNT/E). Free vibration tests are used for characterization the damping properties through the exponential decay response of the tested materials, while the frequency response function (FRF) is used for determination the storage and loss moduli. The storage moduli (flexural moduli) and loss moduli of the investigated materials were determined using free vibration tests as a nondestructive technique. The storage modulus of MWCNT/E nanocomposite was improved by 7.3% while the storage moduli of QI-GFR/MWCNT/E and UI-GFR/MWCNT/E are reduced by 9.1% and 5.2% respectively. The experimental investigations reveal that the addition of 1 wt% MWCNTs improves the damping ratio of the newly prepared materials in some cases to about 100%.

“…The heterogeneous behaviour of these materials makes their damage analysis very important (Hills et al, 1996;Adams et al, 2000;Davidson et al, 2010;De Moura et al, 2011). One of the main failure modes of layered composites is the delamination fracture, which can occur because of machining errors, or low velocity impact during the service life (Rizov et al, 2005;Zammit et al, 2011;Chaudhuri and Balaraman, 2007). One of the critical failure of these materials is the buckling caused by uniaxial compression (Tarján and Kollár, 2010;Klobedanz, 2014).…”

a b s t r a c tIn this work we analyse the buckling process of composite plates with trough-the-width delamination and straight crack front applying uniaxial compression. Local, global and mixed mode buckling cases are considered. The novel part of this work is that the distribution of the resulting in-plane forces is taken into account for the analysis of the buckling of the delaminated plate portions. For determining the behaviour of the delaminated plate with respect to the external compression, first an analytical method is given for determining the global critical loads. Second the local critical forces are determined using a finite element model. For this analysis a semi-discrete element was developed for the delaminated plate portions. The analysis was carried out using the method of harmonic balance because of the distribution of the in-plane forces along the delamination front. The buckling process of the plate with respect to the axial compression is determined from a displacement controlled model.
