It’s of great engineering value for the variation of a functional with a dual function and of second derivative under the moving boundary condition.In this paper
we construct the functional expression according to variational theory
and then derive the Euler-Ostrogradskii equation and the corresponding transversality condition.According to the ordinary equation and the transversity condition
we then solve the deflection and critical load for a circular plate contacting to the substrate under the uniformly d...
