Third Order Overall Potential Energy, Governing Equation , Flexural Rigidity 3rd Order Functional

For Clamped Clamped Fixed Fixed plate, whose vertical axis rest on clamped and fixed supported edges while the horizontal axis rests on also clamped and fixed boundaries, forming a plate of CCFF shape orientation, remains the plate of focus in the work. Third order energy Functional was adopted in the research work. The clamped clamped fixed fixed plate was considered as the direct independent plate, meaning that the material properties are uniform round about the shape of the element. These includes the flexural rigidity, poison ratio and young elastic modulus of elasticity. Considering the plate arrangement, the shape functions were first formulated, after which the various integral values of the differentiated shape functions, of the various boundary conditions were all generated. Next to this was the formulation of the stiffness coefficients for the various boundary cases. Further minimization yielded the controlling functional known as the overall potential energy functional. The differential value of the Third Order Overall Potential Energy Functional, with respect to the amplitude was further integrated. The integration gave rise to the result known as the Lead equation. From the lead equation comes the derivation of the non-dimensional buckling load parameters. The rest of the analysis which is detailed below was conducted using the buckling equation
