* As a rule, keeping the
neutral axis close to the center of the stack will equalize tension and compression forces so that neither will become too extreme.
The adhesive was located above the
neutral axis (the horizontal at a distance of h/2) on the left side of the line where the load was applied and under the
neutral axis on the right side of the line where the load was applied.

neutral axis, and top and bottom fibres across the span.
(1) Section plane remains plane after loading; this assumption ensures that the strain at any point of the cross section is proportional to its distance from the
neutral axisThus stress-strain distribution in the section changes and depth of the
neutral axis increases, new flexural stiffness is created.
Normal stresses that act on the infinitely small side area dF, disposed at the
neutral axis y can be calculated:
For hardness measurement nine indents were made in transverse orientation in the extrados, intrados and
neutral axis location.
Analytical Procedure to calculate Flexural capacity The position of the
neutral axis in the Brick-FRP composite beam is shown in Fig.8 which was determined using equal forces (C = T) concept.
