Abstract : The equations of motion for a shell are developed in general orthogonal coordinates using Hamilton's principle. They are modified to yield a set of improved equations which are then transformed to helicoidal shell coordinates. The membrane portion of these equations are solved for the natural frequencies and associated mode shates for a uniformly twisted membrane boundary value problem. (Author)
