    The nature of polyethylene pipe failure | plasticstoday

    17/11/· Early 1960''s research of HDPE pipes established three major failure modes for PE pipe: ductile failure (mode I), brittle failure (mode II) and brittle/chemical failure (mode III). Ductile failure was associated with yielding and reflected a material''s propensity to undergo large-scale, irreversible ''plastic'' deformation when under stress, the yield stress describing the load intensity at which Puhui Pipe manufacturer in China
