Thin Plates with Rapidly Varying Thickness, and their Relation to Structural Optimization,e thickness plates is a case in point: for certain problems, plates with “stiffeners” formed by rapid thickness variation can be stronger per unit volume than any traditional, uniform or slowly varying plates. To resolve such a design problem one must introduce a “generalized plate model,” represent
