An analysis is presented of the axial compression of non-circular prismatic sections, based on the existence of velocity discontinuity lines. Equilibrium equations are written along the ‘flow lines’, and theoretical pressure distribution curves are calculated in different directions and compared with experimental measurements. The theoretical pressure hills and lateral deformations are in good agreement with the experimental observations.
