Is it possible to apply sigma_x+sigma_y values, as the individual stress values like sigma_x and sigma_y are not available.

Hello everyone, Usually, the displacement or loads will be applied as boundary conditions to solve the problem. I would like to apply sigma_x+sima_y as input and solve the problem. Let us assume, sigma_x+sigma_y results are available from some another source like experiments over certain nodes...

I do appreciate you guys for your continuous support. I got good insight into the problem.

The goal of the analysis is to apply the experimental strains and perform stress analysis in FEA. Are there any tools for performing inverse FEM?

Sorry, I have edited the question. I am having strains(E11,E22,E12) from experiments and convert them to displacements(U1,U2).

How can I convert nodal strains to nodal displacements? Is there any built-in Abaqus facility for doing this? I have E11,E22,E12 from experiments at all nodes and would like to convert to U1,U2.

I have the strain data (at all nodes) from the experiments. I would like to apply this strain in FEA at all nodes. Thanks for your quick reply.

Hi, In Abaqus, we can apply displacement, velocity or acceleration as boundary conditions and solve the problem. In the similar manner, how can I apply strain as boundary condition and solve it? I have gone through the Abaqus documentation and could not find it. Any help is greatly appreciated...
