I am working on a design for a telescoping manhole system that relies on shear failure of High Density Polyethylene pins. Can anyone tell me what the shear strength of HDPE is, or where I can find this information?
The Shear strength number is a short term property. As you know, these properties are time, temperature and load dependent. You may want to apply a conservative approach to avoid a creep failure.
I'm pro HDPE (we manufacturer HDPE pipe and fittings) but why HDPE for the pins?
