Formability of a non-crimp 3D orthogonal weave E-glass composite reinforcement
No full textIn this paper, the formability of a single layer E-glass non-crimp 3D orthogonal woven reinforcement
(commercialized under trademark 3WEAVE by 3Tex Inc.) is experimentally investigated. The study
involves the forming process of the 3D fabric on two complex moulds, namely tetrahedron and
double-dome. The tests are assisted by 3D digital image correlation measurement to have a continuous
registration of the fabric local deformation. Moreover, the results of bending tests in warp and weft
direction are detailed to enlarge the mechanical properties data set of the 3D reinforcement, necessary
for understanding its deformability capacities in forming processes. The elevated bending stiffness of
the 3D fabric means that use of a blank-holder during forming is not required. The reinforcement has
a good drapability and it is able to form complex shapes without defects (wrinkles and fibre distortions).
The collected experimental results represent an important dataset for numerical simulations of any
complex shape with the considered 3D fabric composite reinforcement
Newcomer Student-Athlete Perceptions of Coaches’ Socialization Strategies: Scale Development
No full textIn this era of multi-million dollar paydays, the need to fill arenas and the pressure to win has increased dramatically. In order to build a winning program, the coaching staff turns to national and international recruiting. According to David Ching, Senior Contributor of Forbes, “Nearly every Power Five college athletics program spends more than $1 million per year on recruiting” (Ching, 2018). The fact that student-athletes have a limited time of four years of eligibility to perform for their institutions, results in a continuous influx of newcomers to the team. Student-athletes with a diverse cultural background have to adapt to a team culture in order to be able to perform at the highest level. Every sports team is situated within a unique environmental context (i.e., physical, task, social, personal) that is characterized by a distinct social reality (Martin, Bruner, Eys & Spink, 2014). Considering that, the integration of newcomer athletes is a process that happens on a large scale at the beginning of every season, delineating the tactics sports teams employ to facilitate this process warrants considerable attention (Benson, Evan, & Eys, 2016). Theory regarding organizational socialization offers a promising framework to examine how sports teams manage initial entry experiences because it presumes that teams are active agents in newcomer socialization – using tactics that ideally combine to maximize outcomes for the individual as well as the group (Van Maanen & Schein, 1979).
In collegiate athletics, the head coach has a major leadership role within the team. The high salaries that head coaches receive are just a reflection of how important the coach vi is within the collegiate athletics model. Nevertheless, very little is known about the effectiveness of the socialization process of student-athletes with a different culture (SADC), established by the coach.
In this study, the author focused on the organizational socialization process of newcomer student-athletes that have a significant difference between their culture and the team culture (e.g. a student-athlete from California who attends an institution in South Carolina). The author took special attention to the student-athlete’s perception of the ability of the coach to structure the socialization process. Based on the results from Jara-Pazmino, Heere, Regan, Blake, and Southall (2017) that state that each athlete has a different background and different factors that influence their reality, which might hinder the effectiveness of universal treatment.
Jara-Pazmino et al. (2017) proposed the use of a socialization process with five constructs (custom coaching, mentorship, team structure, all-inclusive family and support services). For this study, the author has conceptualized the five concepts proposed by Jara-Pazmino et al. (2017) based on an extensive literature review to coach’s cultural competence, mentorship, introduction to norms and roles, prosocial behavior and introduction to support services. Coaches face a challenge when trying to find a balance between accommodating SADC and findings ways to create a homogeneous culture for their team. For this reason, the purpose of this study is to develop a valid and reliable instrument to measure the SADC’s perceptions of the tactics used by their coach during the socialization process of newcomers into college athletics, based on the scale development procedure by Churchill (1979)
Shear Behavior of a Non-crimp 3D Orthogonal Weave E-Glass Composite Reinforcement
No full textIn this work, the deformability of a single layer E-glass non-crimp 3D orthogonal woven reinforcement is experimentally investigated.
The attention is mainly dedicated to the behavior during shear loading because this is considered the primary deformation mechanism in the reinforcement shaping. The mechanism occurring when the material is subjected to in-plane shear is studied by two different tests: bias
and picture frame. The nonlinear response of the material from both tests are compared in term of macroscopic shear force vs. shear strain. The shear deformation is observed and measured at the macroscale, to have the initiation of wrinkling phenomenon, as well as at the unit cell level to study sliding and rotation of the tows. For these
purposes, the tests are assisted by digital image correlation (DIC) technique
Micro-CT analysis of the internal deformed geometry of a non-crimp 3D orthogonal weave E-glass composite reinforcement
No full textAn investigation at the unit cell level of the sheared geometry of a single layer E-glass non-crimp 3D
orthogonal woven reinforcement (commercialized under trademark 3WEAVE by 3Tex Inc.) is performed
by X-ray micro-computed tomography (micro-CT) observations. The aim is to observe, understand and
quantify the effect of in-plane shear deformation on the composite reinforcement geometry, at mesoscale
(i.e. unit cell level). It was observed that, increasing the shear deformation, Z-yarns maintain
unchanged the distance between the yarns and as consequence the yarn cross-section has a reduced variation
of width, mainly in the weft direction.
Furthermore, the effect of the shear angle on the textile thickness during compression is measured, this
being an important parameter after the forming and molding phases of a composite component production.
Compression tests and micro-CT measurements of the thickness show similar values and are in
agreement with the prediction obtained assuming the theoretical invariance of the volume in the considered
range of shear deformations
EXPERIMENTAL FORMING OF A NON-CRIMP 3D ORTHOGONAL WEAVE E-GLASS COMPOSITE REINFORCEMENT
No full textThis work illustrates the experimental forming of a single layer E-glass non-crimp 3D orthogonal woven reinforcement (commercialized under trademark 3WEAVE® by 3Tex Inc.). The study focuses on the shaping process of the 3D fabric on two different double-curved shapes, tetrahedral and double-dome. The shear angle distribution on the reinforcement during such shaping is measured by means of 3D digital image correlation (DIC) analyses.
The gathered experimental data are important for the assessment of numerical methods predicting the behaviour of the 3D reinforcement during shaping processes

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Meso-scale analysis of the deformability of a non-crimp 3D orthogonal weave E-glass composite reinforcement
No full textIn this work, an investigation at the unit cell level of the sheared geometry of a single layer E-glass non-crimp 3D orthogonal woven reinforcement (commercialized under trademark 3WEAVE® by 3Tex Inc.) is performed by x-ray micro computed tomography observations. The objective of this study is to observe and understand the effect of in-plane shear deformation on the composite reinforcement geometry at the mesoscopic scale (i.e. unit cell level). For this purpose m-CT geometrical analyses were carried out on a reference sample at the relaxed state and on specimens which have undergone picture frame shear deformation for different shear angles. Furthermore, the effect of the shear deformation on the textile thickness during compression is measured being this an important knowledge after the forming and molding phases of a composite component production
