WebbThe ratio of the moment of inertia of the beam section about the elastic i.e., the centroidal neutral axis to the distance of the most distant edge of the section is the section modulus Z of the beam section. The ratio of the plastic modulus Z p to the section modulus Z is called the shape factor or form factor, denoted by K s of the section. Webbdefinición de neutral axis en el diccionario inglés.

WebbThe maximum shear stress occurs at the neutral axis of the beam and is calculated by: where A = b·h is the area of the cross section. We can see from the previous equation that the maximum shear stress in the cross section is 50% higher than the average stress V/A . Shear Stresses in Circular Sections WebbA beam under bending sees high stresses along the axial fibers that are farthest from the neutral axis.

WebbConsider that the beam is bent into an arc of a circle through angle radians. AB is on the neutral axis and is the same length before and after bending. The radius of the neutral axis is R. Figure 3 Remember the length of an arc is radius x angle in radians 2.2 RADIUS OF CURVATURE Normally the beam does not bend into a circular arc. WebbWhere, c is half the beam's thickness, or in general c is the distance from the neutral axis to the outer surface of the beam. This equation is illustrative for a couple of reasons: first, the shear stress will be at a maximum value at the center of the beam, i.e. when y=0, and will be zero at the top and bottom of the beam.
