Test Case
A block is made of shape memory alloy material. One cycle of uniaxial displacement loading is applied in vertical direction (Figure 475: Uniaxial Loading Problem Sketch). The whole process includes tension, unload, compression, and unload. The whole loading history repeats with body temperature 285.15K and 253.15K respectively. The stress history is obtained and compared against the reference solution.

In the above loading process, the body temperature is maintained at 285.15K and 253.15K respectively. |
Analysis Assumptions and Modeling Notes
The problem is solved using 3D SOLID185 elements. The shape memory thermal effect is defined by TB, SMA. The block is subjected to one cycle of uniaxial tension and compression with body temperature held at 285.15K and 253.15K, respectively. History of stresses in loading direction is acquired in POST26.
