Residual stresses transferred with ISFILE

Residual stresses transferred with ISFILE

Residual stresses transferred with ISFILE

(OP)
I am carrying out a residual stress analysis where in I found stress values are differing by 50 to 70 MPa. Stresses developed in one model are stored using ISWRITE and are read (ISFILE, READ) into different model with similar mesh and geometry. After comparison, the above difference is observed but stress distribution pattern is exactly same. It is changing in numerical value only.

To test this, I have built two similar 3D models with same mesh and material properties. I have used SOILD 185 elements and elastic-plastic material model kinh (multilinear kinematic hardening). It is a 3D vertical block. Top face nodes are constrained in all directions. Bottom face nodes are applied with 1mm displacements in downward direction. Transferred all the stresses to another model. The results are not matching. Can someone please clear this problem ?

With Thanks
Sam
