Numerical Simulations

In this paper, crystal plasticity theory has been employed to simulate the effects of through-thickness texture gradients in the aluminum alloy AA5754 and the effects of strain paths in localized deformation in drawing quality (DQ) steel. It should be mentioned that the finite element meshes employed in both applications consist of four-node quadrilateral elements, made up of four ‘crossed’ constant strain triangular sub-elements. In presenting results, the quadrilateral is regarded as the basic element, and when reporting values of the field quantities the average value of the triangles is associated with the centroid of the quadrilateral.
