I am having problems in writing the umat and uexpan subroutines applicable to the creep model defined in

Has anybody written the algorithm?

UEXPAN

Hi all,

I recently study on a materials's expansion behavior. I am wondering if anyone have used the subroutine UEXPAN. It will much appreicated if you could provide me a sample.

Hope to see some response.

Hi,

I have a thermo-mechanical constitutive model for polymer and want to implement it in ABAQUS through two user subroutines namely UMAT and UEXPAN but I dont know how to use them together. Also, in UEXPAN, I need to pass in the strain tensor as information but I dont see 'STRAN' variable in the list of variables passed in to UEXPAN in Abaqus documentation. Does anyone know answer to this?

Thanks,

Mandar
