Hello everyone, I wrote a Umat subroutine for the 2D Neo-Hookean model, but the results are very different from Abaqus's own Neo-Hookean model. Does anyone know about this? Or does it have a 2D Neo-Hookean subroutine that works properly?
Mohamad Rahmani, perhaps your custom UMAT subroutine for the 2D Neo-Hookean model appears to differ from Abaqus's built-in version. Before investigating further, make sure that your UMAT follows the correct equations and conventions used by Abaqus. For more connect with me on Https://wa.me/+923440907874
