A shear band (or, more generally, a 'strain localization') is a narrow zone of intense shearing strain, usually of plastic nature, developing during severe deformation of ductile materials. As an example, a soil (overconsolidated silty-clay) specimen is shown in Fig.

1, after an axialsymmetric compression test. Motivated by a recently predicted structure of diamond-like BC2 with a high claimed hardness of 56 GPa (J.

Phys. Chem. C, –), we focus on whether this tetragonal BC2 (t-BC2) is superhard or not in spite of such an ultrahigh theoretical hardness. The mechanical properties of t-BC2 were thus further extended by using the first principles in the framework of density Cited by: 3.

Abstract. Localization of deformation is analyzed in elastic-plastic solids endowed with elastic anisotropy and non-associative flow rules. A particular form of elastic anisotropy is considered, for which the localization analysis can be performed with reference to an elastic-plastic solid endowed with isotropic elasticity but whose normals to the yield function and plastic potential are not Author: D.

Bigoni, B. Loret and E. Radi. Many man-made materials and naturally occurring substances are aggregates of crystals, or polycrystals, with a non-random distribution of orientations.

In such textured polycrystals, many macroscopic physical properties are anisotropic, i.e. they depend on direction. This book is about the measurement and analysis of textures, the prediction of polycrystal properties from measured textures and.

The third component of the plastic induced anisotropy, namely the texture formation, is due to the rotation of the single crystals toward a common axis. Such rotation restricts the choice of the available slip systems on which the plastic deformation can take place.
