The conventional representation of a laminated packet of electrical sheet steel as a homogeneous but anisotropic material is extended by treating any butted joints in the packet as a distinct homogeneous, two‐dimensionally nonlinear, material. Its magnetic characteristics are derived from the energy increment that results from closing the gap, obtained by solving the two‐dimensional field problem in the gap region. This technique is rigorously valid for any anhysteretic, nonlinear, anisotropic material.
