Power Curve, ASTM, Plastic Lumber, #1

This program is designed to let members of ASTM fiddle with various criteria for acceptance testing of plastic lumber. As of 3/25/99, it is in draft form. It is likely that it will never be very polished.

Here is the code for the Perl program that handles the data generated by this form. Here is the code for the FORTRAN program that actually performs the simulation. Here is a memo [LaTeX version][postscript version] that describes the program. If you detect any errors in this material, please contact Steve Verrill at sverrill@fs.fed.us or 608-231-9375.

How many secant moduli do you want to consider?

What are they in psi?
(for example, 40000 45000 50000 55000 60000)

How many coefficients of variation (here, 100 x standard deviation/mean) do you want to consider?

What are they?
(for example, 20 for a 20% coefficient of variation)

How many specimens will be tested?
(200 or fewer)

What name do you want for your results file?

The name should be unique to you to prevent the file from being accidentally overwritten by another user.

Since you will see an html document that presents the results as soon as you execute the program, you may not want an ascii copy. However, we do provide this option.

The ascii file will be written in the pub/data anonymous ftp directory. If a file by the same name already exists in the directory, the new results will be appended to the existing file. Check the anonymous ftp link for directions about retrieving the file.

If ftp does not run on your machine, e-mail me at sverrill@fs.fed.us and ask me to e-mail the results file to you. Do this quickly as the pub/data directory is cleaned weekly.
