HDPE Shear Strength
HDPE Shear Strength
(OP)
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?





RE: HDPE Shear Strength
I can not find any data on shear strength.
I also called my Tech Rep and they had no data either.
My suggestion is that you get a piece of HDPE rod and design your own experiment. In that respect, you could validate your design.
RE: HDPE Shear Strength
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?
Good luck.
