bending moment

[′ben·diŋ ‚mō·mənt]
(mechanics)
Algebraic sum of all moments located between a cross section and one end of a structural member; a bending moment that bends the beam convex downward is positive, and one that bends it convex upward is negative.

bending moment

The moment which produces bending at a section of a beam or other structural member; equal to the sum of moments taken about the center of gravity of that section.

The experimental samples that were produced in a way to have four separate samples with radii of curvature of r= 100, 300, 500 mm, respectively, for adhesively bonded curved lap joints with a thickness of h=6.5 mm, a width of w=25 mm and an overlap length of l=25 mm were subjected to three-point bending moment, and damage load results were obtained.
Thus, a reduction in strains under the effect of axial force increases strains under the action of the bending moment.
By performing the numerical analysis with the presence of the tunnel (only no-slip condition is considered here ), the thrust and bending moment contours of lining obtained by numerical 2D and 3D analysis are respectively shown in Figures 18, 19.
Also, a detailed finite element analysis of box and I-girder bridges subjected to AASHTO loading is performed and the results obtained are used to calculate the distribution factors for bending moment which are compared with those found exactly in a similar manner using Australian bridge loading (AS 5100.2-2004).
The IF decreases for both bending moment and deflection, with the rate of decrease increasing sharply for bridges with five or more girders, as the number of girders increase.
where [[theta].sub.i](x), [M.sub.i](x), and [Q.sub.i](x) are the amplitudes of rotational angle, bending moment, and shear force of the section area, respectively.
The beam is in the state of pure bending with constant bending moment M and zero shear stress along the beam.
A plot of the dimensionless bending moment [M.sup.*] = -(100)/[q.sub.t][L.sup.2])M versus the dimensionless parameter [xi] = x/L is given in Figure 3 for increasing values of the nonlocal parameter [tau].
Lu adopted this method and computed the bending moment along the VLFS, where eight submodules were used, and the numerical results were compared to the values calculated by the hydroelastic theory [22].
The Ch1 bending moment, that is, the right-left inclination of the implant-abutment screw during manual application of tightening torque, applied by prosthodontists was greater than that applied by dentists.
Table 4 compares the peak and the mean values of the tower base bending moment obtained from CFD analysis.
We determine its meaning, assuming that the bending moment along the length of the beam is constant:
