instability.<br />

Schematic representation <strong>of</strong> shear band<br />

formation in compression <strong>of</strong> a cylinder.<br />

Rolling direction<br />

Fibrous texture in rolled plate.<br />

•<strong>The</strong> presence <strong>of</strong> preferred orientation causes anisotropy <strong>of</strong><br />

mechanical properties, especially in rolled sheets.<br />

• <strong>The</strong> development <strong>of</strong> texture is the formation <strong>of</strong> deformation<br />

bands or shear bands, which are regions <strong>of</strong> distortion where a<br />

portion <strong>of</strong> grains have rotated towards another orientation to<br />

accommodate the applied strain.<br />
