I am trying to simulate the shape memory effect of shape memory alloys using ANSYS 14 (APDL). I am interested in simulating SMAs heating, while they are in martensite phase. I am using the commands available in the APDL (not USERMAT). My analysis currently starts with the SMAs in the austenite phase and upon loading the SMAs enter the martensite phase. Unfortunately, this is very time consuming and needs substantial computational effort. Any advices are welcome.
Only if you can provide material properties in martensite phase, at least Young modulus and Poisson ratio.
The material properties of the martensite phase and the Poisson ratio can be easily declared within ANSYS (APDL). However, in the martensite phase the transformation strain upon heating (the SMA) is regained. How can the transformation strain at the martensite phase can be inserted in that case?
Dear Aria Tsam,
Thank you for your inputs! However, both works that you recommnded are using USERMAT, which is a user programmable feature. My question though refer to the existing material models of ANSYS 14 (APDL) and not USERMAT. So the question remains, how can I start an analysis with SMAs being in the martensite phase and how can I declare the transformation strain in that case??
Thank you for your effort!
