BEAMS OF COMPOSITE CROSS SECTION:

For beams of composite cross section σx = −Eiky for the ith material in the composite

                     y = yi - y0

y0 is the location of neutral axis from the bottom of the beam.
yi is the location of neutral axis of the ith material. In the figure yi = yA, from this, we get

Where A the area of cross section of the corresponding material.
