Behavior of Fibers in Tension Test

“Since the strength of the fibers in adhesion is very much less than in tension and compression, adhesion enters into nearly every test as an important factor. Thus, if a piece of wood consisting of several fibers is tested in tension, the fibers a and b would probably not break at all, but be merely pulled out, the failure, as far as they are concerned, being due to lack of adhesion and not to a lack of tensile strength. Every tension test presents numerous cases of this king, the broken fibers presenting no even fracture, but being splintered and drawn out especially if the wood is good."—Government Printing Office, 1897
