I am modeling a Thermal stress analysis of 3D wire wherein Temperature field (x,y,z) was imposed by using Interpolation function (imported a .txt file). It is simply an Elastic-Plastic analysis. Because of higher values of imposed temperatures, specimen goes into plastic region. I set the Linear elastic-Perfectly Plastic model (i.e. The plastic region starts when induced stress exceeds the Yield strength of the material).
However, the result are unrealistic i.e. Elastic strain are very low, a zero plastic strain and only thermal strain is very high. I think the total strain is mainly showing up as Thermal strain and contribution of other strains are almost zero.
I have attached the report file. Need help. Any comments or suggestions are appreciated.
