Hi again ;
i want to use a shape memory alloy material ( Ni-Ti for exemple) in RADIOSS
i need your help please
Thanks
Hi,
The best is to use /MAT/LAW65 in Radioss. It’s nonlinear elastic with hystheresis, strain rate dependent, you may also define a plastic region if needed. It is only compatible with shell elements.
There is also a LAW71, specially developed for NItinol with shape memory, but this one is not very stable actually and I would not recommend it.Hence the good choice is Law65 and I would like to add that law71 is Linear elastic before reaching the yld stress transformation.

ok @Rahul R i will do it
Do you have a property of one SMA material??
thanks
Hi Fily,
LAW 65 is compatible with shell elements. So you may have to use TYPE1 property in RADIOSS.
