The damage resulted from excessive longitudinal bending stress
due to the difference between the downward load of cargo weight and the upward thrust of water buoyancy.
To avoid creep rupture failures, the load level used in the long-term tests of Leichti and Tang (1989) was 33 percent of the average short-term capacity, which they noted was close to the I-joist allowable bending stress
2008) also report the mechanism of injury to the trapezoid as an axial load or bending stress
Flexural or bending stress
, combined with other stresses associated with the difference in the coefficient of thermal expansion between the pipe and sealant materials, were the likely causes of the pipe failure," Mr.
With the combination of the reversible bending stress
and torsional stress, failure will occur in very few cycles after the critical stress is reached at the surface.
In order to determine the pure bending stress
in the shaft due only to unbalanced hydraulic forces acting on the mixing impellers (ignoring tensional stress) it was a matter of determining the magnitude of these hydraulic forces and where along the shaft they were acting (impeller location).
They reasoned that a bending stress
was applied to the clip each time it was removed and reattached to the belt and although this stress was well below the fracture strength of the material, the cumulative effect of repeating the bending process caused an initially small crack to grow until it ultimately ran through the whole clip.
This creates precise, dependable welds without bending stress
To the contrary, if only the pure bending stress
is considered, the substrate will warp toward the warmer side after demolding (Fig.
In order to eliminate the main shortcomings of radial harmonic transmissions currently being manufactured--shortcomings mainly due to the constructive shape of the flexible cogwheel and the type of alternating-symmetrical bending stress
occurring in the body of the flexible wheel and of the special ball bearing--there have been new variants developed, that can diminish and even eliminate these disadvantages.
Due to change of geometry, high stresses are induced in this region and net compressive stresses is in the hoop direction and severe bending stress
is in the axial direction.
is about 80% in proximal and distal zones and up to 12% in medial zone.
