An evolutionary problem for the development of a spontaneous structural inhomogeneity is formulated in the framework of energetic solutions. Conti and Theil proved that in the case of an isothermal single-slip crystal, rigid plasticity with no hardening lamellaea form an optimal microstructure. Moreover, their model predicts the existence of a boundary layer which accommodates the lamellar substructure to displacement boundary conditions. It is suggested that the width of the shear and kink bands is a compromise: the minimization of bulk energy tends to decrease their size, while the energy of the band interfaces or the inner structure of the bands opposes this tendency. 2011 BM http://hdl.handle.net/11104/0187453 MATERIALSSCIENCEMULTIDISCIPLINARY|MECHANICS|METALLURGYMETALLURGICALENGINEERING|PHYSICSAPPLIED|PHYSICSCONDENSEDMATTER 1.368 0.41 >10.0 0.02096 0.692 8424 283 44 1.034 31.91 1.33 Q2 56.488 59.909 Q2 Q2 2010 000280819300006 WOS cav_un_epca*0296693 Philosophical Magazine 1478-6435 1478-6443 Roč. 90 č. 27 2010 3729 3742 Taylor & Francis
