“…-then they will know. Thus the countdown"' (quoted in Bogdanovich, 1997). The film conveyed the methodological utility of this idea so successfully that German rocket scientists adopted the countdown as a research procedure, and it has since become the standard protocol used internationally for rocket science (Ley, 1968: 259, n. 5).…”

When scientists act as consultants during the production of a fictional film, it becomes an act of communication that plays a role in the process of science. Fictional film provides a space for scientists to visually model their conceptions of nature. Film impacts scientific practice as science consultants utilize film as a virtual witnessing technology to gather allies among specialists and non-specialists. Film not only has the ability to act as a virtual witnessing technology, but also forces consensus on the public version of scientific debates by presenting a single vision of nature in a perceptually realistic structure. This paper shows films to be successful communicative devices within the scientific community by showing that, and how, other scientists respond to the depictions in the films. It also demonstrates that science consultants use fictional films as promotional devices for their research fields.

“…Global-local finite element approaches have been generally used to manage 3D stress analysis in the case of bonded joints. A 27-node hexahedral solid element has been implemented into the sub-modeling function of ABAQUS for the 3D stress analysis of composite-toaluminum bonded joints [23]. BOGDANOVICH and KIZHAKKETHARA [24] used a global-local type sub-modeling approach with this 27-node solid element of ABAQUS to analyze the double-lap composite bonded joints with adhesive layers.…”

Abstract: Efficient bolted joint design is an essential part of designing the minimum weight aerospace structures, since structural failures usually occur at connections and interface. A comprehensive numerical study of three-dimensional (3D) stress variations is prohibitively expensive for a large-scale structure where hundreds of bolts can be present. In this work, the hybrid composite-to-metal bolted connections used in the upper stage of European Ariane 5ME rocket are analyzed using the global-local finite element (FE) approach which involves an approximate analysis of the whole structure followed by a detailed analysis of a significantly smaller region of interest. We calculate the Tsai-Wu failure index and the margin of safety using the stresses obtained from ABAQUS. We find that the composite part of a hybrid bolted connection is prone to failure compared to the metal part. We determine the bolt preload based on the clamp-up load calculated using a maximum preload to make the composite part safe. We conclude that the unsuitable bolt preload may cause the failure of the composite part due to the high stress concentration in the vicinity of the bolt. The global-local analysis provides an efficient computational tool for enhancing 3D stress analysis in the highly loaded region.

“…However, the use of complex 3-D model for this kind of analysis has been limited to few cases in recent years. The problem of a bonded joint was investigated the interfacial stress distribution along the bond line [10][11][12]. Little analysis has been conducted in bonded/bolted joints.…”

The performance of composite repairing using single lapped joints is sensitive to factors such as ply stacking sequence of laminate, bonding surface preparation, anisotropic nature of adherend, as well as bearing and load transfer from one adherend to the other. This research is focused to investigate the stress distributions in laminated composite joints with multiple pin loads using finite element analysis. The structural response of various configurations of single lap joints, namely bonded, bolted and bonded-bolted joints, are analyzed by three-dimensional finite element method. A comparison of the results obtained using finite element analysis is conducted with experimental results and the results are validated. Parametric study is conducted to investigate the effect of stress distribution and load transfer due to ply stacking sequence of laminate.
