A plastic may be selected for a thin web application by finite element analysis of the part including the properties, including Poission's ratio of potential polymers from which the part may be made and subjecting the computer model of the part to loads to determine the deflection of the part under a specified series of loads or when the part breaks or subjecting the part to a number of use cycles to determine when the part fails. The process is iteratively repeated for each plastic and the results are compared to select a preferred plastic for the part.

Method of selecting a plastic

A lightweight concrete composition containing from 10 to 90 volume percent of a cement composition, from 10 to 90 volume percent of particles having an average particle diameter of from 0.2 mm to 8 mm, a bulk density of from 0.03 g/cc to 0.64 g/cc, an aspect ratio of from 1 to 3, and from 0 to 50 volume percent of aggregate; where the sum of components used does not exceed 100 volume percent, and where after the lightweight concrete composition is set it has a compressive strength of at least 1700 psi as tested according to ASTM C39 after seven days. The concrete composition can be used to make concrete masonry units, construction panels, road beds and other articles.
