Computational Methods for Laminated Glass

AbstractAn existing, recently developed solid-shell finite element is proposed for efficient and accurate modeling of laminated glass structures. The element is applied to one test example treating a thin laminated glass structure subjected to biaxial bending and the performance concerning accuracy and efficiency is compared with standard three-dimensional solid elements. Further examples illustrate how the element could be applied in the modeling of laminated glass structures with bolted and adhesive joints. For these examples, experimental data for relevant quantities are provided as a comparison. It is concluded that the element is an excellent candidate for the modeling of laminated glass.

Designing Bolt Fixed Laminated Glass with Stress Concentration Factors

Abstract A general method for determining stress con centration factors for laminated glass balustrades with two plus two bolt fixings with variable positions is developed. It is demonstrated how the stress concentration factors can be presented graphically in design charts and representative charts are displayed for the case of a more specific bolt-fixed balustrade type. In general, the use of simple formulas and design charts allows the maximum principal stresses of the balustrade to be determined for any relevant combination of variable geometry parameters involved.

Large-scale mortality shocks and the Great Irish Famine 1845-1852

Abstract This paper considers the consequences of a large scale mortality shock arising from a famine or epidemic for long run economic and demographic development. The Great Irish Famine of 1845–1852 is taken as a case-study and is incorporated as an exogenous mortality shock into the type of long-run unified growth theory pioneered by Galor and Weil (1999, 2000), and modelled by Lagerlöf (2003a,b) among others. Through calibration, the impact of such a mortality shock occurring on the cusp of a countrys transition from a Malthusian to a Modern Growth regime is then depicted.
