Mashing
Wires are flattened and
spread at broken ends.
Check on all the above
conditions for mechanical
abuse, or either abnormal or
accidental forces during
installation.
Corrosion
Wire surfaces are pitted with
break showing evidence
either of fatigue tension or
abrasion.
Indicates improper
lubrication or storage.
Abrasion plug Fatigue
Reduced cross-section is
broken off square thereby
producing a chisel shape.
A long term condition normal
to the operating process.
Abrasion plus Tension
Reduced cross-section is
necked down as in a cup and
cone configuration. Tensile
break produces a chisel
shape.
A long term condition normal
to the operating process.
An example of interstrand and core-to-strand nicking. A strand (upper member) has been
