Spaces of the Past, Histories of the Present: An Interview with Stuart Elden and Derek Gregory
No full textThe ontologies of space and territory, our experience of them and the techniques we use to govern them, the very conception of the socio-spatial formations that we inhabit, are all historically specific: they depend on a genealogy of practices, knowledges, discourses, regulations, performances and representations articulated in a way that is extremely complex yet nevertheless legible over time. In this interview we look at the logic and the patterns that intertwine space and time — both as objects and tools of inquiry — though a cross-disciplinary dialogue. The discussion with Stuart Elden and Derek Gregory covers the place of history in socio-spatial theory and in their own work, old and new ways of thinking about the intersection between history and territory, space and time, the implications of geography and history for thinking about contemporary politics, and the challenges now faced by critical thought and academic work in the current neo-liberal attack on public universities and the welfare stat

Nanoindentation of neat and in situ polymers in polymer-matrix composites
No full textNanoindentation experiments were performed on neat and in situ polymers in two different composite materials (IM7/977-3 and AS4/APC-2) and an adhesive (FM 300). The objective was to determine whether differences in modulus and hardness result from composite manufacturing procedures. Since the aim was to measure material properties, acceptable comparisons with neat properties could only be made using unconstrained, cured in situ tests. Measurements of modulus and hardness were made using two different techniques on two different indenters at a range of loads and penetration depths. The load–penetration depth data from the neat and in situ tests were compared to determine whether the fiber constraint affected the in situ tests and quantitative measures were implemented to determine whether an in situ test was unconstrained and therefore acceptable. The results of this comparison between neat and acceptable in situ tests showed a clear increase in modulus and hardness for the cured in situ materials, indicating that the materials are modified in some fashion by the manufacturing process. A finite element analysis of the in situ indentation experiment was performed to determine the required size for a polymer pocket that would minimize the constraint of the fibers on the polymer deformation response
James Bond: international man of gastronomy
No full textThis article is concerned with the representation of food and drink in Ian Fleming’s James Bond novels. In particular, it examines how the author uses Bond’s culinary knowledge and habits of consumption as an important constituent of his hero’s character. Similarly, the food choices of other characters, notably villains, are shown to be linked, by Fleming, to core aspects of their identity − principally their ethnicity. Bond’s impulse to observe and classify, very much in evidence in the novels’ food sequences, is examined in terms of the texts’ construction of Bond as a skilled identifier of signs
Modeling inelastic matrix crack tip deformation in a double cantilever beam specimen
No full textA finite element model is created to investigate the contribution of inelastic matrix deformation at the crack tip to the composite toughness in a double cantilever beam specimen. The constituent properties are explicitly incorporated into the analysis using a global-local model and discrete fiber and matrix layers in the local model. The results indicate that there is little difference between the global and local J-integrals for matrices that do not exhibit pressure-dependent plastic deformation. Plastic deformation occurs in matrix layers away from the crack tip, but the majority of the deformation in terms of strain intensity occurs in the resin-rich region at the crack tip. This localized intensity causes the crack tip strains and plastic energy dissipation levels to be much higher in crack tips that are highly constrained by the layer of fibers, even though plastic volumes are lower. The results shed new light on previous explanations for the difference between ductile matrix and composite toughness and the thickness effect observed in adhesive bonds using ductile adhesives
Constituent and composite quasi-static and fatigue fracture experiments
No full textQuasi-static and fatigue Mode I fracture experiments were performed at a variety of loading rates and temperatures using a polymer-matrix composite (PMC) (IM7/977-3) and its neat resin (977-3). Neat resin quasi-static toughness showed slight increases in toughness with increasing loading rate and no dependence on temperature until the test temperature neared the glass transition temperature, where the toughness decreased. Composite quasi-static delamination initiation toughness showed no clear trends with respect to temperature or loading rate, but toughness values were generally higher at higher temperatures. Composite fatigue delamination onset and crack propagation rates were strongly dependent on temperature, with delamination onset occurring at a lower number of cycles and crack propagation rates being higher for a given maximum applied strain energy release rate. The neat resin fracture mechanisms were a key factor in explaining the composite quasi-static and fatigue behavior, but no quantitative predictions of composite fracture behavior could be made since the crack tip mechanisms apparently changed

A fiber bridging model for fatigue delamination in composite materials
No full textA fiber bridging model has been created to examine the effects of bridging on Mode I delamination fatigue fracture in a carbon fiber polymer–matrix composite. The model uses a cohesive zone law that is derived from quasi-static R-curves to determine the bridging energy applied in the bridged region. Timoshenko beam theory and an iterative self-consistent scheme are used to calculate the bridging tractions and displacements. After applying the bridging model to crack propagation data the scatter in the data was significantly reduced and clear trends were observed as a function of temperature that were not apparent previously. This indicated that the model appropriately accounted for the bridging in the experiments. Scanning electron microscopy crack opening displacement measurements were performed to validate the model’s predictions. The measurements showed that the predictions were close to the actual bridging levels in the specimen
