Maximum fiber stress
and maximum strain are calculated for increments of load.
Similarly, bottom fiber stress
(f b) at support was: f b = f c2 + f c3b = 922.6 -1416.13 = -493.53 kN/m2.
The macroscopic damage and failure criteria for fibrous composites do not consider the micromechanical properties of interface, such as fiber stress
distribution, stress concentration, shear strength, and frictional shear stress on the debonding interface.
It can be seen that the outer fiber stress
of the as-peened 304 SS strip ([epsilon] = 0) and bent strips with strain [epsilon] lower than 0.58% are compressive, while the strips bent at strain higher than 0.66% show tensile stresses.
No difference in modulus of elasticity and modulus of rupture, work to proportional limit, work to maximum load, or fiber stress
at proportional limit between samples steamed following treatment and those only treated was shown.
Much like a drinking straw, this tube has little resistance to collapsing when it is bent sharply or kinked, again leading to fiber stress

Machining the surface of the raw log also creates a perceived material strength loss in that stress concentration points initiate fractures and effectively reduce the calculated extreme fiber stress
Kawaguchi (5) presented a viscoelastic model of PET superdrawing, relating the fiber stress
as a function extension as follows, with good agreement with experimental results:
Before radiata pine can be accepted into ANSI 05.1, test data must be provided to support the ANSI-designated fiber stress
. This study presents an evaluation of radiata pine poles grown in southern Chile following the guidelines established by the ANSI 05.1 standard for approval of foreign species.
In a dilute or semidilute suspension, the fiber stress
due to an ensemble of rigid particles can be obtained by integrating over the stress fields generated by single particles .
The ASA committee, which later became the ANSI committee on wood, adopted fiber stress
values for wood poles partially on the basis of results presented by Wood  and partially on the basis of established precedents.
