Constitutive equations describing rigid‐plastic compressible material behaviour are derived taking into account a strength‐differential effect. Basic systems of equations according to the slip‐line and finite element methods are introduced. Solution algorithms combining the FE and SL‐methods and solutions for stationary and unsteady processes are presented.
