Large Deflections of Helical Springs

The problem analyzed is that of a helical spring subjected to end couples and forces which produce large deflections of the spring. These deflections are such that the angle of rotation of one end of the spring centerline with respect to the other end of the spring centerline exceeds the range within which small angle approximations are possible and may be as large as (pi) radians. The spring is treated as a prismatic bar with known compressive, bending, and shear rigidities. These rigidities are functions of the pitch of the spring and therefore change as the spring is deformed. Furthermore, the spring rigidities assume different values along the length of the deformed spring as the pitch varies from point to point along the deformed spring centerline.
