Anisotropic materials in curved geometries Answered

When using the geom bend command, a rectangular mesh can be bent into an arc. If I assign a transversely isotropic material using the stiffness tensor input, I assign Cij entries that correspond to different directions in Hooke's law. Are these stiffness entries mapped according to the global coordinate system after bending (output xcrs,ycrs) or the initial coordinate system (output xcrd,ycrd)? In other words, is the bending transformation also applied to the stiffness tensor? I've attached a drawing to help illustrate my question. Thanks for the help.

    The geom bend command only bends the geometrical structure and not the material properties.

    You will need to apply a local cylindrical axis definition for the anisotropic material and apply it to the material using matr axis command.
