View ArticleShape memory alloy material models including plasticity implemented in ABAQUS
I am working with shape memory alloys (nitinol), and am in that respect investigating fracture behaviour of NiTi, using, among other things, simulations in ABAQUS. ABAQUS doesn't have a material model...

View ArticleSubroutine simulation migration from HETVAL to UMATH
Hi!I'm already simulating a shape memory alloy behavior with the aid of the HETVAL subroutine, but I'd like to use UMATHT instead, since the HETVAL can't simulate correctly heat absortion(cooling...
View ArticleOn superelastic bending of shape memory alloy beams
In this paper, a closed-form solution is presented for bending analysis of shape memory alloy (SMA) beams.
