Abstract We consider either a perfectly flexible membrane or a material surface not perfectly flexible, the latter endowed with a structure and subjected also to distributed external moments.

When some discontinuity is present in the material, the classical version of the work-kinetic energy theorem is no more valid in either case. However the theorem is still valid under suitable conditions on the physical objects. Here we obtain the conditions to be imposed in the above mentioned cases.
