Efficient equilibrium-based stress recovery for isogeometric laminated curved structures
No full textThis work extends the stress recovery for laminated composite solid plates, proposed in [1,2], to curved structures. Based on 3D Isogeometric Analysis (IGA) computations and equilibrium, this procedure uses a single element through the thickness in combination with a calibrated layer-by-layer integration rule or a homogenized approach, allowing for an inexpensive and accurate approximation in terms of in-plane stresses (and their derivatives), while through-the-thickness stress components are poorly approximated. Relying on the highorder continuity properties of IGA shape functions, an accurate out-of-plane stress state can also be recovered by means of direct integration of the equilibrium equations in strong form. The a posteriori step application, which is straightforward in the context of solid plates, is not trivial in the case of curved geometries. In fact, the notion of in-plane and out-of-plane directions is not clear when modeling this kind of structures in the global reference system, while adopting curvilinear coordinates to express the equilibrium gives rise to additional coupled terms that require an iterative process to resolve the balance of momentum equation. Therefore, we propose to apply the recovery locally, which, despite leading to more elaborated stress derivative terms because of the increasing geometry complexity, still allows for a direct reconstruction as the resolvent system is uncoupled. Several numerical results show the good performance of this approach particularly for composite stacks with significant radius-to-thickness ratio and number of plies.MN
A rigorous and efficient explicit algorithm for irreversibility enforcement in phase-field finite element and isogeometric modeling of brittle crack propagation
No full textIn the present work, a computationally efficient and explicit algorithm for the rigorous enforcement of the irreversibility
constraint in the phase-field modeling of brittle fracture is presented. The proposed approach is staggered and relies on the
alternate minimization of the total energy functional. The phase-field evolution turns out to be governed by a complementarity
boundary-value problem, where the complementarity stems from the irreversibility, while the boundary-value problem is
originated by the presence of the gradient term in the phase-field functional. Several different techniques have been proposed in
the literature to account for damage irreversibility in a computationally effective way. Following a similar approach proposed
in the past for a gradient-plasticity problem, a particularly simple and effective solution strategy based on the Projected
Successive Over-Relaxation (PSOR) method for constrained optimization, where an iterative explicit scheme is used for the
solution of symmetric linear complementarity problems, is presented. Even though the proposed method is restricted to linear
complementarity problems, it can be applied to the numerical simulation of a wide range of problems discussed in the literature.
The performance of the suggested solution algorithm on a number of test cases is compared with that of a recently proposed
penalty approach for the approximated enforcement of irreversibility

Autoimmunities after COVID: An Interview with Cindy Patton
No full textCindy Patton is Professor Emeritus of Sociology and Anthropology at Simon Fraser University in Vancouver, Canada. An early AIDS activist in Boston, she holds a PhD in Communications from the University of Massachusetts, Amherst. After inaugurating her academic career at Temple University (Rhetoric and Community) and Emory University (Graduate Institute of the Liberal Arts), she accepted a Canada Research Chair in Community, Culture and Health at Simon Fraser (2003-15). In that capacity, she worked with more than two dozen groups to develop small community-driven projects related to HIV/AIDS, housing, social welfare, mental health, while achieving, culminating in the creation of the Community Health Online Digital Research Resource, a catalogued, open-access, full-text collection of the materials from those groups (www.chodarr.org). Her academic publications span the social study of medicine, especially AIDS; social movement theory; gender studies; and media studies. She is the coeditor of Queer Diasporas (2000) and a special issue of Cultural Studies on Pierre Bourdieu (2003). She is the author of such works as Globalizing AIDS (2002), Cinematic Identity: Anatomy of a Problem Film (1997), Fatal Advice: How Safe-Sex Education Went Wrong (1996), Inventing AIDS (1990), and LA Plays Itself/Boys in the Sand: A Queer Film Classic (2014).
Taken collectively, Patton’s scholarship and activism has laid the foundation for insights in the health humanities, particularly AIDS studies, that consider the inextricable connections between epidemiology and ideology. Patton’s theorizations of stigma and discrimination patterns, her deconstruction of “truth” discourses subtending science, her critical re-evaluations of axioms associated with risk, safe sex, community, and knowledge production have been crucial interventions in the understanding of health and illness as cultural and discursive scripts. Among Patton’s most enduring contributions has been her theorization of how “African AIDS” was invented and circulated—that is, the notion of geographically bifurcated HIV pandemics split by the essential linkage between Africa and blackness generally with pathogenesis. Equally influential has been her elaboration of the insurgent queer research practices that fused with antiracist struggle to combat this split.
In the interview below, Travis Alexander and Nishant Shahani engage Patton in a discussion on a range of topics—from (dis)continuities between the HIV/AIDS and COVID pandemics to the role of queer activism in forging epidemiological counter-publics and the geopolitics of medical bureaucracy
Higher order phase-field modeling of brittle fracture via isogeometric analysis
No full textThe evolution of brittle fracture in a material can be conveniently investigated by means of the phase-field technique introducing a smooth crack density functional. Following Borden et al. (2014), two distinct types of phase-field functional are considered: (i) a second-order model and (ii) a fourth-order one. The latter approach involves the bi-Laplacian of the phase field and therefore the resulting Galerkin form requires continuously differentiable basis functions: a condition we easily fulfill via Isogeometric Analysis. In this work, we provide an extensive comparison of the considered formulations performing several tests that progressively increase the complexity of the crack patterns. To measure the fracture length necessary in our accuracy evaluations, we propose an image-based algorithm that features an automatic skeletonization technique able to track complex fracture patterns. In all numerical results, damage irreversibility is handled in a straightforward and rigorous manner using the Projected Successive Over-Relaxation algorithm that is suitable to be adopted for both phase-field formulations since it can be used in combination with higher continuity isogeometric discretizations. Based on our results, the fourth-order approach provides higher rates of convergence and a greater accuracy. Moreover, we observe that fourth- and second-order models exhibit a comparable accuracy when the former methods employ a mesh-size approximately two times larger, entailing a substantial reduction of the computational effort
Dialogical Self: Author and Narrator of Career Life Themes
No full textThis conceptual paper introduces the Theory of Dialogical Self to the career development literature. The life themes component of the Theory of Career Construction is the focus of application for dialogical self. It is proposed that the notion of dialogical self may contribute to understanding how individuals construct the career-related life themes. Dialogical self is thus presented as a promising theoretical construct to augment the explanatory capacity of the Theory of Career Construction and the constructivist, narrative approach to career theory in general. Implications for career counselling are presented
