Within continuum dislocation theory the plane constrained uniaxial extension of a single crystal strip deforming in single or double slip is analyzed. For the single and symmetric double slip, the closed‐form analytical solutions are found which exhibits the energetic and dissipative thresholds for dislocation nucleation, the Bauschinger translational work hardening, and the size effect. Numerical solutions for the non‐symmetric double slip are obtained by finite element procedures. (© 2009 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
