Hi everyone, This is my first time posting here I am looking to get some help with Abaqus, I wish to compare two models and find the residual stress which causes a original model to deform to the other. The deflection between the two models can be calculated by other software. I plan to do this by setting displacement boundary conditions to a number of node points the model which will force the first models mesh to deform the the shape of the other. Abaqus would then calculate the resulting stress which, if I am correct, would be the negative of the residual stress in the original part. At the moment I am manually setting known displacements as boundary condition to nodes a simplified mesh over the original model. I was wondering if there was a way to directly set the displacements as the second model to give a more accurate result. Thanks for any input.
