METHOD OF SELECTING A PLASTIC

摘要

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.
