[PSUBS-MAILIST] Information Needed for HDPE

Below are the Mechanical properties of the pipe. I'm unclear what I should
input into in your xls file. I have located the Posions Ratio which is .4.

First, I'm still looking for my data / tables. But !...go back to "matweb"
http://www.matweb.com/search/SearchSubcat.asp
under the search for "Thermoplastic Polymers" go down to the
"polyethylene" . HDPE is listed in this category. However, be
ready for a long list ! Look on your HDPE pipe for any coding.
This may give you a clue as to the type.
