We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Using *ELEMENT_SHELL_COMPOSITE, the through-thickness integration points are located at the center of each of layer.   *ELEMENT_SHELL uses Gaussian integration by default.   Integration point locations for Gaussian integration are tabulated under *SECTION_SHELL in the User's Manual.   I would expect Gaussian integration to be more accurate.   If you increase the number of layers in *ELEMENT_SHELL_COMPOSITE, I would expect the solution to improve.
