Unusual characteristics of mixed mode delamination fracture in the presence of large scale bridging
No full textThe unusual characteristics of mixed-mode delamination fracture in the presence of large bridging zones of through-thickness reinforcement are explained through an idealization of the mixed-mode bending specimen. With simple but realistic constitutive laws assumed for the bridging mechanisms, beam theory offers insightful analytical solutions and illuminates the length scales that control the crack characteristics. Of particular significance is that the mode I energy release rate can vanish after a period of crack growth, due to the bridging effect of the through-thickness reinforcement. This crack tip closure phenomenon is one manifestation of bridging-induced spatial oscillations that sometimes appears in the crack displacement function, which can be understood qualitatively through the similarity of the fracture problem to the classical problem of a beam on a Winkler foundation. The possibility of crack closure and consequent crack arrest has important consequences for designing certifying tests for laminates with through-thickness reinforcement and predicting strength and lifetime
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Intramolecular Catalysis in the Enolisation Reactions of 4-Oxoheptanedioic Acid and its Monoethyl Ester
No full textMode I Weight Functions for an Orthotropic Double Cantilever Beam
No full textApproximate weight functions are proposed and validated numerically for an orthotropic double cantilever
beam (DCB) loaded in mode I. They define the stress intensity factor at the crack tip due to a pair of
point forces acting on the crack surfaces and have been deduced from the corresponding isotropic result
using an orthotropy rescaling technique. The weight functions allow mode I large scale bridging problems
in beams and plates to be formulated as integral equations, in terms of stress intensity factors at the crack
tip, without the limitations imposed on accuracy by beam theory approximations. The proposed functions
are applied to investigate the influence of the orthotropy of the material on the fracture behavior of DCBs
in the presence of large scale bridging
