Can objects perform?: agency and thingliness in contemporary sculpture and installation

In his 1967 essay, “Art and Objecthood”, Michael Fried bemoaned the theatricality of minimalist sculpture, which replaced the presentness of compositional sculpture with the staging of an experience for the viewer as performer. His argument has since been inverted by artists and art writers invested in the idea of sculptures as props forming part of an artistic experience economy. This discourse has accompanied the rise of relational aesthetics as a dominant paradigm for contemporary art. More recently, however, there has been a turn away from relationality to ‘object-oriented’ art, where objects are seen to stage their own theatrical experiences, performing themselves without requiring the activation of a viewer’s body. We trace parallels between the philosophy of Bruno Latour and the “Speculative Materialism” group and this emerging trend in sculpture. In ascribing agency to objects, Latour proposes a radical shift from philosophy’s traditional investigation of the relationship between the mind and the world. Drawn to the idea that matter can be creative, artists have embraced his thinking. However, we argue that this has lead to a generalized, universalizing humanism that disables political action. Moreover, it undermines the potential for anti-humanist critique latent in object-oriented philosophy.

A novel bogie design made of glass fibre reinforced plastic

This paper presents a completely new design of a bogie-frame made of glass fibre reinforced composites and its performance under various loading conditions predicted by finite element analysis. The bogie consists of two frames, with one placed on top of the other, and two axle ties connecting the axles. Each frame consists of two side arms and a transom between. The top frame is thinner and more compliant and has a higher curvature compared with the bottom frame. Variable vertical stiffness can be achieved before and after the contact between the two frames at the central section of the bogie to cope with different load levels. Finite element analysis played a very important role in the design of this structure. Stiffness and stress levels of the full scale bogie presented in this paper under various loading conditions have been predicted by using Marc provided by MSC Software. In order to verify the finite element analysis (FEA) models, a fifth scale prototype of the bogie has been made and tested under quasi-static loading conditions. Results of testing on the fifth scale bogie have been used to fine tune details like contact and friction in the fifth scale FEA models. These conditions were then applied to the full scale models. Finite element analysis results show that the stress levels in all directions are low compared with material strengths.

Modelling the structure of a polymer glass poly(methylmethacrylate) through neutron scattering experiments

Determination of the local structure of a polymer glass by scattering methods is complex due to the number of spatial and orientational correlations, both from within the polymer chain (intrachain) and between neighbouring chains (interchain), from which the scattering arises. Recently considerable advances have been made in the structural analysis of relatively simple polymers such as poly(ethylene) through the use of broad Q neutron scattering data tightly coupled to atomistic modelling procedures. This paper presents the results of an investigation into the use of these procedures for the analysis of the local structure of a-PMMA which is chemically more complex with a much greater number of intrachain structural parameters. We have utilised high quality neutron scattering data obtained using SANDALS at ISIS coupled with computer models representing both the single chain and bulk polymer system. Several different modelling approaches have been explored which encompass such techniques as Reverse Monte Carlo refinement and energy minimisation and their relative merits and successes are discussed. These different approaches highlight structural parameters which any realistic model of glassy atactic PMMA must replicate.
