Protective Structures

This article studies the feasibility of using geodesic domes as expeditionary protective structures, since they are fast-assembly lightweight structures and are able to withstand very heavy loads due to their specific geometry. A 6-m standard International Orginization for Standardization container is used as a benchmark structure for the study, which is developed using the nonlinear explicit code LS-DYNA. The blast simulations were performed with the Load Blast Enhanced option, using the phenomenological Johnson–Cook constitutive model to reproduce the behaviour of steel subjected to a large range of strain rates. The performance assessment of the protective structures under blast loading was based on the evaluation of the associated safety zones inside the protective shelter as well as on the characterization of the potential structural damage. With the additional insights provided by this article, it is possible to identify some of the competitive advantages shown by this type of structures which will hopefully foster new advances in the field.

The paper covers static and dynamic testing of structural building steels grades B500A and RB500W in tension and compression under wide range of strain rates. The spilt Hopkinson bar technique apparatus is used to investigate the dynamic behaviours both in compression and tension. A detailed knowledge of mechanical properties of those steels at different strain rates at two modes of large deformation is crucial, because the steels are the most commonly used in building structures as well as in protective structures due to their good strength characteristics.

AbstractElectromigration experiments have been carried out on simple Cu dual-damascene interconnect tree structures consisting of straight via-to-via (or contact-to-contact) lines with an extra via in the middle of the line. As with Al-based interconnects, the reliability of a segment in this tree strongly depends on the stress conditions of the connected segment. Beyond this, there are important differences in the results obtained under similar test conditions for Al-based and Cu-based interconnect trees. These differences are thought to be associated with variations in the architectural schemes of the two metallizations. The absence of a conducting electromigrationresistant overlayer in Cu technology, and the possibility of liner rupture at stressed vias lead to significant differences in tree reliabilities in Cu compared to Al.
