Parametric plate element analysis was prefenced Kirchoff theory application.
Parametric method for plate element analysis than isoparametric applications is more complex.But isoparametric method application has not Kirchoff theory.This region was improved Reissner for Mindlin Theory. This method was utulized isoparametric plate,shell etc. structral member areas.Reissner theory sub element`s is shape function quadratic plane stress elements.This quadratic element models are 4Node-8Dof (Bilinear), 8Node-16Dof(Serendipity),9Node-18Dof (Quadratic),sub functions. Nevertless high order element model is description 9Node-26Dof main shape function (Heterosis)model. Generally applications has not select 12Node
or 16Node quadratic sub functions models. Because more node force and moment effect is zero.

Element has parametric stiffness matrix tranform for depend to Jacobian transform partial isoparametric formulation. Notice this analysis is NOT ISOPARAMETRIC MODEL.Only parametric integral transformed isoparametric integration. Numerical integration method is selected Gauss Legendre Numerical integration Method.
