ABOVE-GROUND HIGH DENSITY POLYETHYLENE (HDPE) PIPE …

Asuming the same conditions as Example 2, what would the maximum theoretical force developed on the unrestrained end of a PE pipe if the other end is restrained? The cross sectional area of the pipe wall is approximately 1.5 in2, the temperature change is instantaneous, and the frictional resistance against the soil is zero. σT = α (T2-T1) ES
