“…The constants, , , Substitution of Equations ( 7) into equilibrium equations given by Eqs. (A3) supplies the following five highly coupled fourth order governing partial differential equations [69,73]: In what follows, the above system of five partial differential equations is solved in conjunction with the SS4 type simply supported boundary condition, prescribed at the edges, 1 0, x = a , and 2 0, x = b , which are given as follows:…”
