Statics of Rigid Units Chain

The statics of one-dimensional rigid units chain subject to stretching force is analyzed. The potential energy of adjacent units interaction is assumed in the simple periodic form (harmonic in the small distortion limit). The position angles of subsequent units are given by the system of two iteration equations, one of them being irreversible. The derived system of equations exhibits interesting properties significantly different from those of the standard system which describes the chain in the harmonic approximation.
