UMAT for Shape Memory Alloy (Nitinol) plastic behavior in Abaqus

Hi,

I want to perform nitinol plastic behavior in ABAQUS, and there were two related article:

Answer ID: 1658 : UMAT and VUMAT routines for the elastic-plastic simulation of Nitinol

Answer ID: 4699 : Abaqus/CAE plug-in utility to calibrate Nitinol material behavior

But the website http://simulia.custhelp.com/cgi-bin/abaqus.cfg/php/enduser/home.php is not available.

Could anyone help me?

Thanks
