Shearing stress distribution in typical cross-sections
Shearing stress distribution in typical cross-sections: Let us consider few examples to determaine the sheer stress distribution in a given X- sections
Rectangular x-section:Consider a rectangular x-section of dimension b and d
A is the area of the x-section cut off by a line parallel to the neutral axis. is the distance of the centroid of A from the neutral axis
This shows that there is a parabolic distribution of shear stress with y.
The maximum value of shear stress would obviously beat the location y = 0.
Therefore the shear stress distribution is shown as below.
It may be noted that the shear stress is distributed parabolically over a rectangular cross-section, it is maximum at y = 0 and is zero at the extreme ends.
