I am trying to model an anisotropic material of the Holzapfel form in ABAQUS for a tubular artery. I am having trouble creating the local fiber orientations. I am using ABAQUS 6.13.
I have created a local material orientation in CAE and assigned a global orientation with a cylindrical CSYS with axis 1 pointing radially and an angle offset to the theta(2) direction at the given angle of 38 deg.
Is this correct? I also tried the discrete orientation option and the results look similar to the global one.
Kindly help me out. I am really stuck.
