Double Glazed Units (DGUs) consist of two glass panes held together by structural edge seals. Calculation methods for DGUs consider that actions applied on one pane develop effects in all the panes, due to the coupling from the entrapped gas. Various methods have been proposed in standards to evaluate this load sharing, which depends upon the stiffness of the glass panes, the thicknesses of spacer and the size of the DGU.
A comprehensive analytical formulation, the Betti’s Analytical Method (BAM), has been recently proposed to calculate the load sharing in DGUs of any shape, composed by glass panes of arbitrary thickness, with various support conditions at the borders and various types of external actions, including concentrated and line loads. Simple expressions can determine the gas pressure as a function of a universal shape function, which coincides with the deformed surface of a simply supported plate, of the same shape of the DGU, under un

That mask in your coat pocket, the one you bought from a group of well-meaning volunteer seamstresses at your church and which you wear while out shopping? What is its particle filtration efficiency? How good is it at keeping the coronavirus from spreading?

After more than a year of widespread community use of them, the masked landscape still very much resembles a modern-day version of the Wild West, with little in the way of standards or regulation. There is undoubtedly a great amount of care and love put into every mask sewn by benevolent organizations, but it’s likely their rigorous testing falls sh
