Problem 5.2: The differential equation governing axisymmetric bending of circular plates on elastic foundation is given by

where is the modulus of the elastic foundation, is the transverse distributed load, and

Develop (a) the weak form and identify the primary and secondary variables, and (b) the finite element model. Note that the shear force is defined by
